I think your thoughts and feelings about sex should be just that - your thoughts. What your friends do or dont do in the bedroom is really no concern of yours and shouldnt really influence the way you feel about sex. It's fine if your friend is just casually talking about life and sex comes into it, but it's a little unfair on his girlfriend if he is actively going out of his way to tell people - namely you - about their sex life. Especially if she is under the illusion that nothing is going on. Remember, if she found out, not only would she be annoyed at him, but she'd also be annoyed at you. Your friend might start the conversations, but you could easily stop them if you wished. Also about the porno thing - sex is never like it is in porn films. That's just unrealistic. But you may be finding out recently that there's more to it than you first thought - I know when I was younger I imagined sex to just be missionary position, the same thing again and again.

They showed me this picture of 3 oranges and a
pear. They asked me which one was different and
did not belong. They taught me different was
wrong."
