To try or not to try...

So i've been talking with a couple of girls lately. I have been naked in my bed with both (not at the same time though hehe) and with both i lost my boner when i was putting the condom on. They are like two possible hook ups.
The thing is that the last time, when i met with one of them, the worst happened, and so had happened the time before that, and the one before.
Im on a pretty good streak right now, i intend to keep it, and i know i can.
A great part of my motivation for doing a reboot (take it as long as it may) is that i want to be able to have real sex, with real women, and really conect with it all.
So this weekend i could end up in bed with one of them, if i wanted to. Maybe even both (again, not at the same time). But i dont know if i should.
On one hand i wanna have sex with them really bad, and i know that sex helps rewiring. On the other, im afraid its too soon, and that i will loose the boner again (and who knows how many times either of them will stand that?), but if i dont have sex with them soon they'll loose interest!?

Any advice?
Please
Thank you

 

Well it's been 11 days since I last fapped and 17 days since I last watched porn.
