Help!!!

Do you girls have fantasies? Does your man?

My boyfriend has been pushing me and pushing me to have a threesome so he can fuck someone else.

I’m not okay with it. Yeah I like girls and shit and it would be cool to experiment but he wants to actually have intercourse with them and it’s a turn off for me. I don’t want to share him with someone else. I just don’t know what to do because he gets so mad when I tell him I’m not into him doing that with someone else.

Advice anyone?
