I am a seperated guy who is a single full time dad. When i was married i had a normal sex life, and still maturbated then, as i do now.
i was masterbating long before i ever had sex and my hand has always remained faithful to me, its always does it the way i want it done, it doesnt have periods or get headaches.
When i was younger sometimes after masterbation i would feel guilty, i could never work out why. These days i just say to myself, is masterbation enjoyable? Yes it is. Its better to have a wank than rape somebody.
I feel masterbation is something that i will have forever, if my wife is gone i will still be satisfied to a large extent due to wanking.
