I like my sensitivity. It’s supposed to be sensitive there for pleasure. I’m not trying to need little blue pills 20 years from now.
Yes they do, pop over to pegym.com and find out for yourself I have been doing them for around 14 years but most of that is for maintenance to maintane my size I'm up to about 8 inch's which I like, but it takes time and your get longer and thicker, if that is what you want. Puts me in the 2 inch's of gain the last inch come in the last 3/4 years and its not a quick thing to happen, takes deadication and time, I did mine with breaks and the wife loves it.
We lose erections because our mind is not on the job we are doing, its all to with what's up top and the way we are thinking.
I think this largely depends on the person. There are a lot of variables that affect arousal, pleasure, and erections. It’s not the same for everyone.
Kinda half cut, too....covered to the tip soft and the whole head is exposed hard - but it's loose enough to easily pull up over the head jerking off. It's kind of the best of both worlds.
I like the kinds where the tip is fully covered by the foreskin, leaving a small "nub" of skin at the tippy top.
Completely covers when relaxed, but when erect draws back about 1/4 over the head to expose the slit.
