If mean she/he wants you as a girlfriend/boyfriend
He wants to move upstairs.
If it was your boyfriend that probably means he wants to hold your hand or something. Or never let you fall which technically means let you down, or it could mean that he wants to hold you up.
it means your not putting out enough and he wants to sleep with someone else,
Either he wants to kiss you or he want to eat you out. If you dont know what that is, google it
It is a colloquial (slang) reference to his desire to ejaculate on you.
Probably wants a kiss. Or has chapped lips.
it means he wants to have kids
He's weird or sick of you and wants to be able to sleep with other people too.
If your boyfriend says that he wants to have a child but not with you, that just means that he's not ready for that type of a commintment, and if he says that if it happens then it happens that just means that he will be there for you. He will help you through it.
not neccesarily he may just want some time to calm down :)
NO WAY, he just wants to sleep
