does she undress before you? i had a girlfriend like that, We would have sex and then she would ask me to close my eyes so she could get dressed, it was sort of odd, but she felt better that way.
i had sex in the subway, it was funny seeing the look on a womans face when she figured out what we were doing, also in the back of a movie thearter, it works reallly well if the girl wears a short skirt, just some advice.
if it gets really bad they make some cream for the genitals (i forget what it's called)
I think the best is a vibrating butt plugg, that way you can jack off and still stimulat the prostate
i've had sex with my cousin, The First time is the most akward but it gets better and better after each time. you really need to use protection though.
