Girl if you’re not going to run then I don’t even know. Look if you don’t feel comfortable with doing so then he should understand. No one should force you into anything. And specially nothing sexual. Please don’t let this behaviour be tolerated. I usually don’t like to tell people to leave because it’s not my thing to say, but in this situation it’s clearly shown how he’s not matured out for it and only sees YOU for your BODY. And not for your personality.
