Fuck no! If all you want is a slick dick, find someone else who's willing. You've already detoxed from her and it will only mess with your feelings or hers to start shit up again

Short answer: NO!
The only sex you should or could have after a break-up is break-up sex within 1 week of breaking up. You both still have feelings and it´s just a mindf**k if you hook up with her again. Jealousy and resentment will follow. Just allow yourself and her to connect with new people and soon enough someone else will feel way more attractive than your ex. Trust me on this! Been there done that and not going to make that mistake again.
