Is masterbating wrong when you're intimate with someone? My girl got mad at me when she saw me jerking off to a picture of a woman.

There's nothing wrong with it. Men masturbate all their lives and look at pictures while doing it. Women masturbate all their lives too, but usually don't look at pictures.

Women (and I include me) do not understand why a man prefers to look at photo of some strange woman than a person they love. So women get upset bcause thy think they think thy are not good enough.

The solution is - do it - just don't let her see you do it.

The reason is men look at other women/ pictures is that we are primitive, neanderthal hunters whose actions are governed by obsure, complicated instincts not easily understood...
An analogy...men are always looking for that prize "deer". They hunt for weeks, going up every back road they can find. Eventually, they sit in that blind in freezing cold temperatures in camoflauge clothes, rubbing on deer urine, drinking beer, freezing their butts off just to shoot a deer, then drag it out of the woods 10 agonizing miles to the car, taking 1 hour to painfully lift and strap it on the roof, take it home 100 miles...lucky not be picked up for weaving all over the road, all smelling like billy goats, hang it in the garage, take pictures, laughing and then don't have the foggiest idea why they do it or what to do with the deer....

The same with men and hunting women, they hunt down, catch, take home a woman, and don't have a clue what to do with them once they get nekked. Then the woman has to show them what to do....which they forget.... so repeated efforts here become downright embarassing. Then, they bitch to all the neighbors if they decide to live with her a while and wonder why they ever did it..
So, looking at pictures or films, and masturbating avoids all this embarassment, but satisfies their primitive, cro-magnon, gorilla-like desires and instincts....it's all part of the HUNT!

The reason I think she is mad is because that picture of a woman was her mom. I love my girl just that it was morning and I had a hardon. I just needed a picture of a woman so I can jerk off. She still looks young for her age too. I think it's not wrong to masterbate as well.

If I was your girlfriend I would be upset too. You are not an animal. I am sure you can find something more appropriate than that. I am sure she saw this as a sign of disrespect for her mother.

Also -whose photo was it? If it was her framed photo, or a snap shot lying around I can imagine she thought you might ejaculate on it and ruin it.

Your girlfriend must have a sexy looking mom (cougar). Some young guys prefer looking at older women to get turned on. Just look at Ashton Kucher and Demi Moore or Justin Timberlake and Cameron Diaz. Young guys and older women. How about the reverse. Old guys and young girls. Tom Cruise and Katie Homes. Damn, I watch too many tabloid shows.
