Guilt after sex

I’m 23 so I’ve been with guys before ( ones who didn’t deserve me May I add ) and so I was celibate for a long time nothing with anyone the other day I hung out with someone who I’ve been intimate with before & we ended up having sex , now I have this guilty feeling wishing I didn’t even do anything with the loser , maybe I feel like this because he hasn’t said anything to me besides like alittle bit the day after , but now I’m just mad at myself for even messing with him again knowing he’s the fuckboy type , I don’t plan on ever being with him again but I don’t know how to stop this feeling of guilt I feel like I just put my feelings in someone else’s hands which they haven’t been in a long time .
