No. Doesn't always mean he's trying to have sex. It means if like if y'all haven't held hands he wants to hold hands, if y'all haven't kissed he wants to kiss, if y'all haven't had oral he wants oral, and then sex.
The Laurenpaige girl is right! It doesn't mean only sex! It could just be kissing! We don't know how far you are in your relationship so you will just have to make the judgment what one step further actually is! Good luck:) (don't do anything you will regret!)
