We've had sex outside 100s of times, so been there, done that. But I know she used to have sex in front of her bf's roommates way back in the day, but she had never done that with me. So, she probably would have loved if her friends watched us, but then she would have been so upset with me the next day for letting it happen and not stopping her. One of those "it's not creepy if you do it while drunk, but if you do it when you are not drunk that just makes you a creep" type things. Bummer.
