Hi,

I'm 22 now and still a virgin(lol). I'm not ugly or fat or something but I'm just so fucking shy around girls. When I see cute girls I'd really want to speak with them and have fun in all matters. But my head gets empty when I'm around girls and I don't know what to do with my horniness. My little brother has more experience with girls than me and his current girlfriend is really nice and I like to fantasize about her.
She got some nice tits and her body isn't too bad. I'd love to fuck her and I think she might be interested because she likes to experiment as far as I know. My brother's room is just above my room. When they're having sex I can clearly hear the girl moan and it's so uncomfortable to me. I get horny from her moaning and listen to it while I jerk off. It's a mix of I know I shouldn't be listening to that or even jerk off to that and I'm so fucking horny I would love to fuck her right now.
I'm sexually very frustrated and feel very emberassed every time the topic sex comes up and go all red in my face.

Do you maybe have some serious advice?
