My penis is not huge but have alot of volume. Just about 7" but almost 8" in girth at the widest point. Bout as thick around as your average soda can. At any rate as I am getting older I am finding that maintaining an erection during hard interecourse (i.e. less physically stimulating intercourse) is getting difficult. I get hard just fine and sometimes can stay hard, but often during sex will lose my erection and have to slow down, switch positions etc...to get it back. I have noticed often in big dick porn guys with monster cocks seem to have this problem as well...although mine is far from a monster it def requires more blood to fill up than an average one. Anyone on here have any insight? Would be nice to just fuck on autopilot ofr 20 min and only think of her ya know? I am considering Viagra cause my doc said that as long as the mental stimulation is there the viagra will keep you hard even if the sensation is lacking. Also open to a cock ring but have never used one and am curious about possible dangers. Thanks folks!
