Let us see, now, you are telling her how to regulate her body. She is an adult woman and can do damned well what she pleases.

There are ways, with medical advice to delay the period. That gives a risk of breakthrough bleeding and getting her body off schedule with, perhaps, a month or two of issues with the bleeding. Each different type of pill requires a different approach. When a woman starts messing with her body's schedule, the pill can actually increase the chances of pregnancy. If she wants to talk to her prescriber, that is her choice.

There are two genders - men and women. Each has certain desires with respect to the other and each unique issues to deal with. Men who wish to be with women need to learn that we menstruate, always have and always will. We women learn to deal with it (no choice) perhaps you should as well.

So it is her period. BFD That is no reason to stop having fun.

Hold on a second; what does "she started a week late" mean? Is she being sloppy using her birth-control? Are you being her external memory on reminding her to order it on time? If so, I wouldn't count on it's protection. It may be time to consider a type of BC that suits her better. Certainly pack the condoms to Vegas.

As for menstruation I agree with the other ladies: part of life, deal with it. Packing her necessities and perhaps bring a few specific comforting means with her: painkillers, hot water bottle, that sorta stuff. Making an extra stop at the restroom during travel. Ordering extra towels at the hotel to cover your sheets when it's time for fun :) That's not that hard, is it? At least not for you.

If she considers it a problem and would like to delay menstruation, she could consult with her doctor. As Brandye says: no guarentees. I know women who happily went on holidays with a quick-fix. And I know those who became ill with side-effects during and remained very cranky for some time after. That's her choice. In my experience; holidays and physical regularity usually come with surprises, menstruation and break-through-bleedings one of them.

As men we have to understand and accept that women menstruate. And, as Brandye says: it's her choice if she wants to delay her period. You as a man shouldn't ever try to persuade her into taking pills or make changes in taking them.

And concerning your trip: if you or she don't want to have sex during her period, then don't! There are a lot of other things you can do instead of sex without loosing the romantic feeling of your holiday. I myself is not a great fan of sex during my girlfriends period, and neither is she. So we have found other ways of entertaining ourselves instead of sex. For example a romantic night with a movie and just some nice soft cuddling in the sofa. Don't let her period (if it starts) ruin your holiday! Just use your imagination.

Well said, Runar, and very good advice.

Personally, I find menstrual sex wonderful and have found some partners who agree. A good tip to the maid and some dark towels will appear. Burgundy show less mess than other colours. But I have also found other pursuits whilst menstruating.

Well sorry you're not gonna get exactly what you want on your trip. Sounds like that is more your problem than it is hers. My suggestion, since it sounds like you or she won't consider menstrual sex: Find other ways to be intimate. Getting fucked in vegas shouldn't make or break the trip with a SO and there are other ways to 'get crazy' there, brohan.

Personally, menstrual sex doesn't bother me; it's just an additional body fluid/lubricant. If she is the one against it then you are SOL. If it helps both her and you to hear it, supposedly it helps relieve cramps. Sometimes people are afraid of eating broccoli until you give them a bite with some cheese on it and discover it is not so bad.

I can see the fear of it based on association of serious injury or catching blood born pathogens, which make certain people uncomfortable, but if you're having unprotected sex my friend then the latter is kind of ipso facto anyway. Blood is in no way dirty or icky. Just think of it as another bodily fluid that has color. Maybe it's just me but I find it highly ironic men will gladly put their tongue an inch away from a place where poop exits or have anal sex, but freak out at a little bit of red fluid on their groin. It's okay to get bodily fluids all over my genitals as long as it's the clear kind so that I can't tell it's there...???

If you do decide to go ahead and try it, kudos! simply lay down a towel underneath her. Have a few wet wipes on hand for clean up; I use them with REGULAR sex anyway so it is really no different for me. Whatever you decide, have a great time in Vegas, it's a blast.

If she decides to have sex with you in Vegas (or before), then you will need condoms because if she's had an interruption in her pill cycle less than one month ago she is not protected from pregnancy.

It is not because she's menstruating why I question whether the birth control is reliable. As long as taken as directed, BCP will protect from pregnancies also during menstruation.

It is because the OP has indicated his gf not ordering "on time". Which would make it questionable if she's being sloppy on using it too.
Better be safe than sorry and thus best take responsibility in his own hands bringing condoms. That's all.

It would actually be interesting to know how the trip went :)

This is being made much more complicated than necessary and the trip is likely over by now. The question is simply whether or not to have sex during her period. If each is comfortable with it, get some dark towels and go for it; if not, you have a brief dry period. Those are the breaks.

Birth control is not an issue because the pill is designed to protect by the period, not by the day. I fail to see any issue but, then, I have always enjoyed menstrual sex.
