Hmmm, if I remember correctly, most of the people in that discussion either have girlfriends or sexual partners, and aren’t really practicing semen retention. I think it was Saint that said he doesn’t watch porn or look at sexual things and only has natural sex and stimulation.
When it comes down to it, there’s really only three spectrums I see when it comes to answering your question.
Either one practices SR and releases only rarely, which isn’t for everyone, one does what some guys have mentioned and release once every week or two…
Or they fap when they feel like it.
I take it your question lies more along the lines of what are other things people do instead of retention when not in a relationship, right?
