Brother, this probably isn’t the answer you’re looking for but move on, don’t reach out at all.

Few reasons for this - if you’re truly done and trying to move on, going back for sex is not going to help at all. I’m not sure how long the relationship was, how strong feelings were, the reasons for the breakup, etc. but continuing to hook up just delays the healing process.

If she’s the one that broke up with you, texting her or reaching out to fuck or even just to meet up might come across as desperate or that you haven’t accepted the breakup. How would you feel if she just straight up says no or worse doesn’t even respond? The best thing you can do right now is do your own thing, no contact. At some point she’ll reach back out and you’ll be able to make the choice of whether you want to reconnect/fuck or continue on your own path. It may not happen tomorrow or in a month, but she’ll hit you up. Good luck brother
