Need advise from a non biased source

So I broke up with my ex the person who took my vCard away and also  my first love about 3 moths ago and we broke up  over nothing too serious it just we were always aguing and growing apart so we started to see other people  ... But it seems like he  realized how great of a person I am and he he been basically begging me to get back with him but Im over the whole relationship and don't want to get back with him I just wanna move on which I have been doing but its been no comparison to my past relationship .... Maybe because he was my first love  ... But I just wanna find the right person to be with again so I'll be able to totally move on ... But since the break up I've  been on a dry spell  and I really want to have sex but absolutely not with anyone I just meet or the guys I've been talking to because for one I have morals and for two I don't give my self to anyone that easily and I don't want to add another body count to my list but I've been really Horney and idk if I can wait again to find the right person so I've came to the conclusion of seeing my ex again and having sex with him atleast  one more time to stop the cravings for awhile. but the plan was to not  let my emotions get involved again and you keep it to minimum kissing just basically going a few rounds to get all my sexual fustrations out then Leaving and I'm probably not even gonna contact him much for a while afterwards..... do you think this is logical or am I giving up my sensual brings to somebody who doesn't deserve it and should I just wait ... Happy to get advice from anyone sorry it's so long :) and ofcoure I'll make sure he uses protection and I'll be on  bc don't need no accidents!!!
