Why do I lose my erection when I put on a condom?

I care for my girlfriend, whom I have been seeing for a few months now. I have no problem maintaining an erection when she performs oral sex on me. In fact I can climax twice in a relatively short time. We have, however, been unable to actually engage in intercourse, since when we go to put on the condom, I lose my erection. I'm not really having too much of a problem getting erect (i.e., I get an erection, and may lose it early on, but I am able to get and maintain another one for oral sex). What could be the problem? Stress? A lack of physical attraction? I will be grateful for any answer you can provide me.


How can I get over my hosting anxiety when my friends come to town?

I am a New Yorker who is in college at the moment. Several of my friends from school are living and working in the city this summer, and I love having them around. Whenever I make plans with them, though, I feel a great pressure to make sure they have a good time. As the person who knows New York best (the subway, good restaurants, etc.), I feel like it is my responsibility to make plans and decisions when we go out, and I feel inordinately guilty or embarrassed if the plans ever go awry (e.g., if I mistake the address of a bar, if a restaurant turns out to be unexpectedly expensive, or even if the local subway line unexpectedly switches to the express — things that are often totally out of my control). I know this is silly; my friends can clearly take care of themselves, and I know they don't depend on me for fun. But the pressure that I create for myself is detracting from my own enjoyment. How can I stop holding myself to these absurd expectations and just enjoy myself?


How can I make friends as a commuter student?

I'm currently coming into my second year at a famous but huge university in a big, crowded city. My first year had its ups and downs, but I made a couple friends. The problem is, I commute, and I'm finding it hard socially. I've been depressed for the past year, thinking I'm regressing because I'm not meeting as many people as a normal student would. How does one go from meeting someone in class to hanging out with them on weekends? I feel like I am mostly the one initiating, so I feel like I'm imposing. In addition, the university is rigorous, so I don't always have the time to join the clubs. Any tips on how to make a lot of friends from classes even though I am not dorming?


How do I find out about college parties?

I am a freshman who has just moved into the "social dorm." It's only been a few days, but I already feel like my place in the social strata is being cemented — I'm somewhat overweight, and although I can be very talkative and can force myself to make the effort to meet people despite being nervous, I feel like I'm already being classed as one of the straight-edge less popular types. I don't mind that I'm not the type who makes 500 friends instantly; I'm still managing to make a few good acquaintances/potential friends.

The problem is that the people I make friends with aren't really the party types, and while I'm not a huge party person either, I still want to get to go to some and have the whole "college experience." How is it that other people are "in the know" about parties and stuff like, as soon as they get here? What are the qualities that make them seem to bond so instantly? How do I get myself invited to at least some of these events?? I don't want to crash the parties and show up alone...


Should I start PrEP?

If my husband takes antivirals or post-exposure prophylaxis can we still have sex with a condom and still complete the process like normal? It is affecting our sex life because he does not want to infect me. I don't want to be infected but I knew what I was getting into from the start. I might start PrEP as it is now available to me. What are your thoughts?


Is there a connection between Depo-Provera and hair loss?

I have taken three Depo-Provera shots. My hair started falling out excessively several months ago. In looking for answers I found out that this is a side effect to the shots. I was not informed of that before I took the shots. I saw in one of your Go Ask Alice! answers that depo-provera suppresses the Follicle Stimulating Hormone and the Luteinizing Hormone. What is this hormone? Is this what makes my hair fall out? And do you know if there is anything I can do to stop it? My next shot is due by May 15 but I am not going to get it. Thanks.


What should I expect when I go off of birth control pills?

I've been taking birth control pills for almost seven years and decided to stop taking them as of my last cycle last week. What kind of changes should I be expecting? How long will it take for my body to get used to not having the hormones? In the past few days, I've been feeling very edgy, tired, and with on and off headaches. Is it true that once you withdraw from birth control pills, you may actually lose a few pounds?


Can you be friends with your ex?

I have to ask you a question. I am having a debate with someone as to why your ex cannot be your friend. I'm having a little trouble finding the answer. I need help. So my question is... why is it that you can't be friends with your ex?
