I am a 60 yrs old Indian, had a very active sex life till last year, but i have a problem now:earlier penis outer skin used to go up and uncover front end of penis automatically when erected, till last year. But now outer skin has gone so un-flexible and rigid that it does not gets pulled up and it does not uncover front end of penis; and if pulled back by force , skin gets cracks- this stops erection.skin can be pulled back only in non-erected position....to clean it during taking bath.
is it natural at this age? shud I not think of sex at this age?
