i mean like in everything. from body parts to sexual parts. functioning of the body. emotions. guys look duffer in front of girls. i came to know about period only when i was 15yrs old. the first time i had sex, i was literally serching for the hole (vagina) ha ha. I only knew that girls also masturbate when i was an adult. it took years for me to know that girls don't get aroused just visually. on the other hand girls know each n every physical part of boys n thier sexual needs n behaviour. why? why? why?
