BF has far more experience than me. I never cared, but it's starting to worry me a little. He's tried all kind of things, and I have not.

I think I'm pretty open minded.  I don't know if I should say exactly what I'm open to, but just general ideas are anal, swallowing, a little rough play. I guess it's pretty standard, but I do know some women aren't into those things.

A while ago, I was staying at BFs place while a couple of his old friends from out of town were in.  I wasn't feeling well and went to bed early, while they stayed up drinking a bit.  I woke up later and heard them talking.  He has no idea I heard him, but they were just kidding each other about some girls they know and he said something along the lines that this one girl was the best he'd slept with.  And another girl was really good too but the third was awful in bed.  I know it is an immature conversation to have, but it was just the 3 guys and they were drinking.

My problem:  **I genuinely don't know what makes a girl good in bed**.  I have no clue.  Is he bored with me?  He doesn't seem to have that high of a sex drive with me.  Do other girls do a lot more than I do?  I had to actually have him show me how to give a BJ (and I still am not that great I don't think), but what can I do?  And when we were just friends, he once said in passing that in his experience younger women (like early 20s) are not very good in bed.

This whole thing makes me insecure because I have no idea if I'm good or not, but I'm guessing I'm not that great.  I'm pretty sure I'm not a lot of "fun" (sometimes he can't even finish).  He does watch porn, so that might be causing a problem in his inability to finish, but also those girls are professionals and I have no idea how to compete with that.

Am I being dumb over this?
<bot>: I don't know if I'm good in bed or not but I am worried experienced BF is bored with me or comparing me against girls who were "really good".
