Ehem!!! Masturbation.. Ok, i admit doing it (what more can I do if you are having cyber or phone sex?) And definitely, i'm all alone in my room! First time, can't recall, but it was during my high school days, the age of "exploration" Last time i did it, last week, (but if you mean "when will be the last time", I cannot tell, i'm far from my partner, and it's not as easy to have sexual contact with a real partner (girl!) here in my place as mentioned earlier)
