My aversion to obesity is well known on this site. The best solution is for her to lose half the weight. Then you two can do whatever you choose. She has a lot more than good enhanced sex to motivate her, such as health and limited life expectancy. I doubt that your penis is long enough to gain entrance to the vagina from the rear. In fact, it is likely that much of your sex will be in the folds between the lips rather than in the vagina itself.

I had a fat friend with benefits, we usually did it in doggy style, which seemed to be the most comfortable way.
The best way to know what's best for you is to try different positions that seem comfortable and don't give up if it doesn't work on the first try because it takes time to adapt to a new position.

Good luck!

you could always try having her lay on her back on the edge of the bed and then have her rest her legs on your shoulders, that way you can still rub and tweek her nipples if she is into that.

good ol missionary works really well and doggy style also..what you do is foreplay and then when it comes time to fuck try doggy style and see what she thinks and if you fuck doggy you can reach around and play with her .she will love it and the other hand can grab hher boobs and ay with her nipples

lol sorry i know the spelling and grammer

My wife is a bit on the heavy side as well, but I find that doggy style I can't reach anything on her torso nor her nether regions either.

With her on her back, her butt at the edge of the bed, and her legs resting on my arms, which are by her hips, is really good, the depth is deep, all the way up to my testes, but that makes me go too quick ( think it's when my testes bump up against her that does it).

Might I suggest the cross position that Brandye suggested in another thread. This allows me access to her clit for stimulation (gently), and she really liked it, as I did (check other thread). :)

[QUOTE=jaman;258511]thanks for the help , edge of the bed, legs on shoulders ,this sounds like it will work best ( will definitely be tweeking the nipples ) :)[/QUOTE]

also drop a pillow on the floor, kneel to eat her out in that position. Ask her first. Most women love to receive oral, but she might not. If she likes oral, she'll love that position.

I don't know maybe you could sit on her like the "cowgirl" only in role reversal, call it "cowboy.It's just a thought but it could be worth a try.

As a previously very overweight woman I can honestly say that I never had any troubles with a man being unable to 'find' my vagina. Nor was there ever an issue with them only being able to get part way in because of my fat thighs or tummy and resorting to pleasuring themselves in my external folds. For the record, none of my partners have been monstrously endowed either. I always found that positions just occurred without any pre-planning being needed. Just like everyone else.
Maybe I was never fat enough for this to be an issue? At my max I was 120kgs, but I am 178cm tall. All that said, now that I am lighter and fitter I can maintain some positions for longer than I used to be able. This is mainly for apparent for doggy-style (sore arms) and any form of cowgirl (a small degree of fitness is definitely needed).
I think you’ll be surprised by how achievable a variation of missionary is, even with your weight differences. At my largest I was still relatively flexible and the deck chair and other similar positions worked really well for me and whoever I was with at the time.
If you’ve never been fat it must see truly bizarre that people ‘can’t’ lose weight. As Brandye has said the secret to weight loss is burning more calories than you consume – but it’s what’s going on in a fat person’s head is what stops them from losing the weight, not a failure to grasp this concept.
Losing excess weight is something that everyone should do for their health, but in the meanwhile there is no reason they can’t enjoy sex. In fact, I think that one of the reasons I finally made the required changes to get my body together had a lot to do with feeling happy, sexy, taking pride in my appearance and generally thinking I was worthwhile. Being shamed or bullied into it never worked – it sent me straight to the cheese and dips. However, friendly support and sensitively worded home-truths were very helpful.
Eeek, sorry my first post was so long!

No, it's not too long. You didn't prattle, far from it, you were quite succinct.

Thanks chrisInMs! It's years since I've been on a forum and the post looked a lot longer in the quick reply box than it ended up being once it was posted.

For your information, it is not impossible to have doggy style sex with a woman over 350 lbs. You have no idea what you are talking about. Granted, the positions are limited, but there is no doubt that it is possible to achieve total penetration with a woman of that size. So until you know the facts, keep your comments to yourself.

Yes, jafar, I am prejudiced - against people reducing their life expectancy and their quality of life to the degree that carrying around a few hundred extra pounds will cause. There is no such thing as a healthy 350 pound (160 kg), human body. Period. I know there are "athletes" (Sumo wrestlers, American rules football) above that weight but those bodies will not last. The joints and connective tissue of the human body are not evolved for that and the weight must be lost at the end of playing days. The stress on the cardiovascular system is what shortens lives. And, then we are asked to "heal them" as early death approaches. I am prejudiced.

As for penetration, when I need the assistance of a nurse to gain access for a pap smear I know quite well that access by a penis is limited. Know what I am talking about? Certainly not from firsthand experience. From giving care, yes, I have had patients with an "active sex life" whose vagina was rarely penetrated and whose clitoris was found with difficulty.

If a person has so little interest in life that s/he lives a lifestyle that limits and shortens it, good sex is not usually a priority. I stand by my statement that the best solution for the original post is for his 300 pound friend to lose half her weight.

Sex with a larger woman can cause issues with proper penetration. Just like an overweight man has problems with his fat getting in the way of his penis. My neighbor is well over 300lbs. His wife told me it is much much smaller than when they got together, and the penetration achived is nowhere near as great.

Does it mean anyone and everyone will be unable to have sex? No. I know from personal experience a girl with a larger rear end has some trouble with doggy style. I am not a pornstar but I fall middle of the average range...(which is majority of the population.) She did however have a very large hip circumfrance so even though it was quite arousing watching her dance when it came down to it. I really could only enjoy non rear entry positions.

And I do remember brandye speaking of requireing 2 nurses to hold the "rolls" of a large woman so she could properly perform her examination. It is a pitty to see people who are so content with treating their bodies so poorly. I have a friend who is 19, weighs 320 lbs and has a BP of 170 (I forget the diastolic number). He continues to eat anything and everything. He doesn't care. Why people would want to never make it long enough to see grandkids, or stay content with the self esteem issues and such.

Call me prejudice as well but I am a personal trainer and it amazes me how terrible people treat there bodies. Its one thing to abuse yourself and improve fitness. Its another to abuse yourself and lower your fitness.
