Hey. I'm a 22 yo guy and I recently just got my first girlfriend. I'm very shy and anxious in general, i've never approached a girl before...she was the one that approached me, and really wanted this to happen , was the one that kissed me etc and I feel like she's a keeper in every way.

She kind of figured out that this is my first relationship and probably that I'm a virgin also.

I'm really anxious because of multiple reasons, and I really need someone to give me some tips or advice

She's quite pervy[like find sexual innuendos in everything] and has quite some experience and even though she probably doesn't have much expectations, I'm really afraid because I'm pretty sure that I'm going to fail and because I will have ABSOLUTELY no idea what to do in bed...

The other thing is about my penis. It's like 5" erect and quite thin, and also my skin color around the genital area( like where from the pubic hair starts growing) is much darker than the rest of my body . This drives me nuts even more than my size, because i dont know if it's normal or not...

She did say randomly some time ago that size doesn't matter, but how the guy moves ( which gives me anxiety because of my inexperience and how terrible i'm gonna be ).

I'm really lost, I KNOW THAT I'M VERY LUCKY , and I don't want to lose her under any circumstance..
