How to hookup with your ex?

Hi guys!!

Long story short, my boyfriend and I broke up a month ago from today and I’m super conflicted. I feel as though I’m over him emotionally, since we only dated a few months, but I miss the sex so much. Because of where I go to school and where I live, good options are limited. While we were dating, sex was such a prominent thing for us. We did it a lot. Now i’ve been cut off. Of course sex isn’t a necessity for me, and I don’t absolutely need it, but I see my ex all the time at school and all I can think about is wanting to hookup with him again. We had a fight about stupid things about a week ago, and I ended up blocking his number and snapchat. (He still follows my instagram.) I’m not angry with him anymore but I’m concerned that he will reject me if I ask to hookup. Does anyone have tips on how I could ask? His sex drive is VERY high, so I have sort of a good feeling about it. (Side note: we broke up because we are too different, he was scared of hurting me if we kept dating any further because he has a lot problems that get in the way of him being happy. He didn’t think he was worthy of the love I gave him, which was not true and was heartbreaking to me.)

Please help!

Thanks so much ladies!! ❤️
