I have to say that i have had prem. Ejac. also before PFS. The thibg is that i was almost always honry, and i didn’t need really much stimulation to get a bone. So, i took advantatge of that and used condoms with retardant. Therefore I could mantain a bone without problems, because even with few sensation i keep that bone and i also enjoyed.
However now, i do need much more stimulation and in case i use that condoms, my bone disapears. So, to enjoy sex is much more difficult, because the compromise now is hard to find.
I would say that we are not finishing earlier, but while before pfs we enjoyed and feel honry much early during being with our partner, now we do only feel honry much latter, we do need much more stimulation to feel the hot running through our veins.
