Why does my partner's condom keeps coming off inside?

Quite often when my boyfriend and I have sex, the condom disappears into my vagina. As you can imagine, it is extremely mood killing and a little disconcerting for me to have to reach up there and find it. I read your response to another couple with the same problem, and we'll definitely make sure to hold onto the condom before pulling out. I use Depo-Provera (so the condom is used just to be extra sure), so I'm not particularly worried about pregnancy. What I would like to know, though, is why this happens to us so often? I've never lost condoms with any other partners. I also have the feeling sometimes that it might be coming off before ejaculation. This seems to happen quite frequently (one out of every two or three times we have sex). It's kind of frustrating. Is there anything else we could do differently?


Does your metabolism slow when you hit 30?

I'm a 22-year-old woman. Many of my friends in their late 20s and early 30s (and older) have been warning me about an inevitable metabolism slow-down and subsequent weight gain around my 30th birthday. They say, "You just wait. When I was your age, I sat around all day eating pizza and I never gained a pound. Now I can't lose weight no matter what I do."

I am sure there's some truth to this, but I DON'T sit around eating pizza all day. I run three to four times a week and eat very healthfully. Will these habits ease the slowing down of my metabolism? Or should I expect some weight gain no matter what I do (as they say will happen)?


Is it better to spread out or binge alcohol consumption?

I am a healthy, fit, 18-year-old male. I have tried both ways: consuming small amounts of alcohol regularly (one standard drink a day) and consuming a lot of alcohol irregularly (10 to 20 standard drinks in one night, but only two days a month, or thereabouts).

I have tended towards drinking a lot irregularly because I have found that I can't notice any effects until I have had at least four or five drinks, 80 to 100 proof shots, usually mixed with soft drink.

I was wondering if either way was less healthy or more of a risk as the same amount of alcohol is ultimately consumed. Also, I noticed that I got a bit more of a 'beer gut' when I had one-a-day than 15 at once; is that likely or just my imagination?


How do I use dental dams?

I've seen the recommendations. I've seen the suggestions for do-it-yourself workaround (cutting open a condom, plastic wrap... ). What I *haven't* seen is practical usage advice — how to place the thing effectively, how to overcome the limitations of losing direct contact, how to arrange things to permit vaginal penetration with fingers while still maintaining protection and so on. Best-practice condom use isn't perfectly obvious either, but at the most basic level it's pretty straightforward. If you want to build acceptance for barrier use during cunnilingus, it needs to be at least as clear and/or at least as well-documented.
