If you under 50 and in reasonably good physical health it's all mental. I'm in my early 50s and now seem to have trouble finishing. (Opposite of PE) . I guess in some eyes not a bad problem to have but it does get frustrating when yu can't climax, then it starts to play games on you that yu won't ever be able to finish and feeds on itself- kind of the same way PE is. In my early 40s there were a few occasions were I did PE. Totally didn't expect it (nor did the provider) but I really didn't let it get it to me. I guess that's the key. Try not to let it get to you're head (the head upstairs )I think a lot of it is mental. With a new lover, I tend to not cum very quickly. If the women is tight, or just gave me a great bj, I can't last much longer once I'm pumping away. I also think Viagra makes me cum a little slower too. But if I need to slow things down, just start looking at her tattoos or something, a little distraction for 5 seconds may be all you need to return to fucking away. Also, who cares, if you cum and it feels good for you, the women won't complain. Then spend time making out, massage, etc., then do it again!
