idk im thinking the same thing
you can tell if they are into you and have a craving to always be near you. And they ask you
Sit down with your boyfriend/girlfriend who you trust and can tell each other anything! and just talk about sex and if use are both ready and been going out after a while, why not? but remember use...
they try to jump you in the elevator
communicate! its good to talk to each other!
ask them and test it out
