I am 19. I have never had any sexual experiences with a women. I have actually been too scared to go on with the intimacy because i am so self conscious about my penis size. I guess that since i "missed the boat" so to speak in sex when i was younger, i never knew how i stood on my size. I am a little over 6 inches and i am currently with a women who has had multiple partners. I just dont want to disappoint her, if i'm not "up to par" with the other men she has been with. Any suggestions?
