I'm now 53. MSOG in an hour is almost out of the question for me now. Since I've been hobbying I had one memorable day where I was rabbit style. Many years ago I scheduled for 3 providers in one day. The first was in the AM and the second was in the early evening say 7:PM so no degradation with that time span. However my plan for the 3rd session was to be at Midnight-ish but the provider said can I come now say say 9:PM. I knew performance may be an issue but I said WTF I'm on my way. Once at the appointment, chubby was taking his time getting in gear. No kidding, she realized this and commenced to "handeling" my dick the roughest it's ever been handled before, tugging, pulling, slapping it against my leg, etc.. Surprisingly, my dick responded with one of the hardest dick's I had in my post 20s age. We fucked I came and wow.....a three pop day. My dick was a bit sore afte that but nothing serious.
The PORN factor. I'm not a porn addict, or even watch it very often, only in spurts..pun intended. However, I can jerk off to porn and cum, continue watching the porn (new, different scene) and be hard and ready to pop in 30 - 45 minutes.
The only time I'm able to do this with a lady, provider or not in the last say 8 years is NEVER.
I subscribe to the theory the mind is the best viagra. But it takes two. So if my partner, provider or not, is not say, or does not say, have the ability to bring out the laytent second pop in me I aint gonna happen....in an hour time slot.
