Hey guys, I'm looking for advice...

hmm where to start...I guess I should start at the beginning of my relationship, when I told my girlfriend that I was a virgin, knowing that she was not, and I said that I didn't care about her past, but I also (in a more subtle way, its been a while so I can't remember how I put it) said that I didn't really want to hear about her past sex life.

I have gotten over her past sex life and accepted it, and we have had plenty of sexual relations since then, but what has been bothering me recently is that she will sometimes bring up past sexual experiences when we are "in the act" and sometimes right before the act, and its a rather large turn off. She seems to do it on accident, and always apologizes afterwords.

I think this is my problem, I just need to find a way to get over it. I realize this is dumb of me, but I don't know how to get over it.

she says stuff like "we should try shower sex, it's really good", or crack a joke about the number 69 then say "oh yeah, you haven't ever done 69, its kinda weird" or one time she just asked me "have you ever tried it sitting up before?" and I just said "...you would know...".

and its just little statements like that, that I know shouldn't bother me but they do, especially when where about to make love. and its hard to do anything new with her, because she always has an opinion on it already, and I just haven't formed any of my own opinions on them for obvious reasons.

Sorry for the long post,

TL;DR version: girlfriend talks about how different kinds of sex were in the past, and it turns me off because I've only ever had sex with her so I'm still forming new opinions. and I need a way to get over it.
