Girlfriend no longer attracted to me after masturbating me with her hand

This could be a porn induced phobia but my fear is that if a girl gives me a hand job she'll see suddenly see clearly how small my dick really is . . . or, that I'll look like an idiot when I'm having an orgasm. Sorry if I am touching on an ugly fear that many of us have, but I feel like most men are insecure about some part of their body and being naked in front of their lover means it's all on display.
It's a lot different than making love in the dark!
Also, it's possible that something just snapped within her. It happens. You're with someone for months or even years and all of a sudden you see a different side of them and, after that, you can't unsee it.
Some women might love having a man literally in their hands. But others might find it repulsive.

That's one thought. But, if if I had to bet, I'm guessing it had to do with the argument the next day. That's what orgasms do to us. It's almost as if our reptilian brain wants us to push our lover away after an orgasm, to find fault with her and to find reason to find another mate . . . oh, wait, that's exactly what it's doing! Because this will better ensure the perpetuation of your genetic code. You are a victim of evolution, young man, and your genes could care less about your happiness.

 

It was definitely something else. That one particular handjob didn't end the relationship. On the flip side, It's like saying you blocked her and lost attraction to her overnight because you fingered her.

 

That's never the problem, girls are okay with it, if they are attracted to you. I had girls, where they just start playing with your willy anyway. Because I cuddle them all the time, kiss them, hold there hands, smack there bum, make fun out of them, make them feel loved. This is every day life, not just in the bedroom.

I think she is not happy in the relationship or just found someone else. I think she monkey branched to a guy that she likes more. Women have options. If she says has a close male friend, then this could be the guy. Also sometimes talking to her female friends, if they think your not treating her right or she could do better, they might put thoughts in her head for her to leave.

 

Most women will let you know they found someone else on the very last day.
You may start to wonder: what have I done? it was so fun and lovable.
But they started to lose interest months ago and left you for another when the story between them became serious.
