Help me!!! I've put the condom on backwards when we were drunk and then turned it the right way round. I'm worried about my girlfriend. She is so sweet and kind and does not deserve this. What chance does she have of being pregnant?

This is sort of embarrassing, and you touched on it in a previous message, but... how do you decrease penis size? I'm serious. Is there some sort of surgery? I ask because my girlfriend says mine is too large, and it sometimes hurts her. Please answer.

Is it possible to have too much sex? I didn't see any content on nymphomania. Could you please explain it? Is it considered a disease or something? I'm beginning to think it's a bad thing having too much sex, but it's difficult to consider giving it up; just a mini vacation seems forever and this is for both of us!

Since orgasms cause a release of endorphins into one's cerebral-spinal fluid and endorphins are also somewhat responsible for the emotion of happiness, etc., is it possible that excessive masturbation and/or intercourse would lead to a depleted level of endorphins in the system that could in turn cause one's affect to become somewhat "flat"? Could a sustained low level of endorphins in the system induce depression and/or mood disorder?

1) In my shopping and looking for condoms, I NEVER come across a formal size chart. I have been told that I was "endowed" and that I need to look toward larger sized models, but all I ever see is "snug fit," "large," and "extra large," etc. How big is big? It would be most helpful if I knew what I was buying before I actually bought it. Do you know of the sizes of some popular condoms, or of a size chart resource?

2) I have just started sleeping with my girlfriend and I was a virgin previously. Unfortunately, a slight problem has interfered... I tried to use a condom the first time (a free one from Health Services) and it was too small on me. I only rolled up about 3/4 of the way and was *very* uncomfortable. Is there any specific brand that I could use that would be more comfortable?
