Sometimes when I'm alone at home, I masturbate over my ex girlfriends photos!

Using some local anesthetic I did some foreskin and frenulum streching.

It's a bit tight so I do stretching exercises twice a day for 10 min. In one year I managed to stretch skin to the point I have no problems with pain during sex and my stamina increased for 100% due to less sensitive penis head (still have premature ejaculations, but penetration time has increased significantly and I have lot more control).
