He lasted 4 minutes

I'm so sad right now. I went out of the way to reach out to one of my exes because I haven't had sex in months and we finally did and it was only enjoyable to him. 
He lasted 4 minutes! 
I fell out with my most recent ex but now I kind of want him to finish what the other guy started. 
BUT HERES THE THING.
They're both friends. 
Would I be wrong? Are they going to think I'm a slut, if they find out. 
IM THINKING ABOUT REACHING OUT TO HIM TOMORROW. What do you think?
