The one thing that you can do to be 100% certain is ask him. You can also determine (not 100%) if he likes it if he doesn't tell you to stop.
I know am not a girl, but my boyfriend is my sex partner.
If you just have sex with him, he cheats on you, and just plain ask him.
if you still like them let them know if you don't say F you i hate you
Best way is to ask him
How much time you spend together without sex or just talking about things besides.
He's using her for sex. Tell them to break up.
Yes, if you love your boyfriend and he loves you truly. Then your boyfriend will not pressure you into anything, such as sex.
Tell him he is a bad boy.
If you only go on dates it his/your bedroom.
Mabe u don't do it right or Mabe he don't like sex
To concentrates on the humping
Me and my boyfriend like random sex because we do not get to see each other on a regular basis.
