What do I do??

Omg you guys make having sex sound good af and I want it so bad from my bf but I’m scared that he will be like my last bf and decide that, halfway in my vagina, he doesn’t want to and then breaks up with me... I want to have sex and I know he does too! I mean I’m turned on by the way he looks at me sometimes! He looks at me like I’m a snack and I want him to throw me on a bed and fuck me. I’m on my period right now and idk how he would feel about it but I was Super horny and I really wanted it tonight... what do I do???
