If you have read other posts here, you would of found many of them containing the exact same questions you have. You're NORMAL, stop overanalyzing everything and relax and enjoy sex.

Bigger men complain about that all the time. She shouldnt say anything to you and enjoy what she has. Work out and see what happens.

> i don't know if these things are normal so i have to find out.

The great thing about the condition of normalcy is that it is what it is for you.

> first off, im not sure if i have a low sex drive or not. i think about it all the time, but i probably only masturbate once every 2 or 3 days. i just don't get that urge to do it multiple times a day.

This is well within the range of normal. Sure, some of us masturbate once, twice, thrice, a day, yet "normal" can be any frequency from this or more, down to once every four-five days. That you think about sex all the time indicates that you have a "normal" sex drive. That you only act upon those urges every few days is not unusual.

> i find it kinda hard to maintain a constant, rock hard erection for long periods of time...but while i'm taking care of her needs my wood just kinda drifts away, and when she's done sometimes its a bit of a struggle to get it hard again, even though i'm super horny.

This is also not unusual. Have you asked her to continue stimulating you as long as he has the composure to do so?

As for regaining your erection, first off, stop ruminating about your performance or abilities. Concentrate on the matter at (in) hand. Make sure your penis is well lubricated. If you continue to have difficulty rebuilding an erection by her actions, then take matters into your own hand and see how it goes. (Contrary to popular belief, you do not need an erection to experience an orgasm--although it certainly helps.)

There are going to be times, albeit rare, when a guy just struggles and struggles to reach an orgasm almost to the point of exhaustion, but for you to have a continual problem is unusual. My first thought is that if you can easily rebuild an erection via masturbation, yet find it difficult to rebuild it from her efforts then my recommendation is what it always is--teach her how you masturbate by guiding her hand with yours several times until she learns to mimic your unique and specific movements, rhythms, and pressures. Key to this is also giving her feedback on how you are responding and for what you may need.

> my gf makes jokes about it going soft because its hard for my body to keep it full of blood because it's "so big" (her words, not mine.) could there be any truth to this?

Pure balderdash. No truth whatsoever.

I agree with SLP; your girlfriend, perhaps well-meaning, needs to button her lip and not offer chiding quips. She needs to know about and understand the Fragile Male Ego and how it affects a man.

I urge the two of you to spend lots of time concentrating on each other's arousal and making certain that one or the other of you is not left behind.

> but we couldn't get it in because she's a smaller girl, and i guess i'm a little big for her. we've had sex twice now, and both times she's just kinda surprised me by jumping on top of me and putting me in her.

...then I guess she is neither too small nor you too large.

> am i going to have to be surprised everytime we do it?

"Whatever works in love and war." If this works well, then use it, or, begin this way and roll over into one of the other positions that you can get into from there. At some future time, just begin with one of these other positions.

> i'm wondering if this might lead to anything bad down the road.

Only if the road becomes bumpy and rough from other causes. Watch out for ruts and do not get stuck in any!

> are there erection exercises i can do?

None that I am aware of. You can exercise your PC muscles, although this has nothing to do with the size of one's endowment.

> should i be on medication?

Not until you determine that your head is on straight and you have stopped worrying about performance and anxiety, and you are relaxed and letting yourself go with the flow--and then maybe not even then.

> one thought that did pop into my head is that maybe she DOESN'T excite me enough?

Only the two of you can make this determination. Attraction is a nebulous entity and is comprised of pheromones, visual as well as auditory cues and aromas; not to forget: "SPARKS!" A couple needs all these elements plus just being chemically turned on from the release of specific chemicals in the brain.

Human evolution has divided the mating game into three components: Lust and initial attraction; Admiration, that keeps a couple together long enough to create an offspring; and Devotion, that keeps the interest in each other alive long enough to raise the child to adulthood and beyond. In part these three phases are chemically driven. The other aspect are noted, above.

> do you think maybe on a subconcious level that may have something to do with my arousal, but i just don't want to admit it to myself?

When we fall in love, we accept the person lock, stock, quirks, and blemishes seen and as yet unseen. If your question has relevance then you need to have a serious talk with yourself, realizing that none of us is perfect--so deal with it.

> P.S.........

One great option is this forum; there are many knowledgeable people who contribute. One thing about being human is that rarely are the things we experience singularly unique.

I hope this is of help. Got more questions?

Well, just my 2 cents worth, it sounds like this is more about anxiety then ED.

I'm not sure about your upbringing (strict parents, strong religious statements against premarital sex/masturbation,etc), but it's been my experience that most erection issues in younger men is due to mental anxiety about the "sin" of what you're doing or thinking!

Can you tell us more about yourself? Age, family issues, religious background, etc.
