I'm wondering if washing immediately and throughly after intercourse helps prevent pregnancy.

1) What exactly is chlamydia? How is it transmitted? Can you get it through oral sex (man on woman)? How is it treated (especially in the case of males)?

2) Could you tell me about the symptoms of chlamydia and if one test is enough to detect that disease? Thank you.

I was just wondering about the difference in effectiveness between "ultra sensitive" and regular condoms. I imagine there is a greater chance of breakage with thin condoms, right? Sorry if this is a silly question, but for some reason, I thought I heard that there wasn't a significant difference.

I have talked to my doctor, to my local Planned Parenthood, and to the local health department. I have gotten the same story from all of them, that unless there are symptoms or a reason, one shouldn't have STD lab work done (or that there wasn't a 'routine' inclusive screen). It wasn't until recently that I discovered that a lot of STDs are asymptomatic. Are there 'routine' tests that should be performed for each of us (besides my normal annual)? If so, where can one go for this kind of testing and what should be tested for?

Recently my girlfriend and I purchased a home pregnancy test and it came out positive. Four days later, we were sitting in a clinic awaiting her name to be called for an abortion. My girlfriend wouldn't hear of any idea but going through the process as quickly as possible.

Throughout the entire experience I tried to be as supportive as possible, taking as much care of her and giving her as much love as I could, and in the meantime suppressing as much of the stress I was under as I could; she has even told me that I was 'perfect' throughout the whole thing. The period following the procedure, though, has been a roller coaster ride: she was subject to mood swings, going from a state of total bliss in my company to practically despising my existence.

She told me she wants time away from me. She is convinced that an experience like this (an abortion) irrevocably changes a relationship. She is pro-choice, but this abortion has affected her more than she expected; she cannot shake the feeling that she killed our child — she has even dreamed about the would-be baby...

Now, I understand that an abortion can bring a person to her emotional knees, regardless of how she might have thought about it previously. But here I am witnessing her shutting me completely out... and I ask myself, is this how it has to be? I love her very, very much — she absolutely means the world to me. She has repeatedly let me know she feels the same about me. How do people deal with this crisis? Is this common? What are the resources available for CU students, post-abortion? How do I convince her that this doesn't have to be the undoing of our relationship, or am I wrong in believing this fate can be avoided?

My boyfriend recently told me that he rarely has orgasms when he ejaculates. I was aware that men could have orgasms without ejaculation, but I didn't think it worked the other way around. Are men more complicated than I thought?

Okay, a question has been asked amongst my friends, and no one seems to know the answer: What is the physiological purpose of the hymen?

I have encountered a problem I never expected; my boyfriend is quite simply very large. I am unable to perform oral sex except for the first couple of inches due to the girth, and vaginal sex is not totally satisfying for him because he is too long and cannot fully penetrate without causing me significant pain. I've seen my doctor, and am reassured that there is physically nothing wrong with me — no infections or scarring, but am finding it difficult to come up with a solution. Any suggestions?
