I think it's a huge turn-on. I got caught once (my girlfriend of the time found a video of me doing the deed on a camera I had) I was embarrassed at first, but once I found out she enjoyed it, I didn't care and she even went as far as letting me suck myself off in front of her (with her help.)
It definitely makes the act more exciting to think that someone might catch you. If I'm licking my cock in my vehicle or sharing stories or pictures on twitter, it makes it much more fun.
In regards to: "I have a close girlfriend who shall remain nameless..
that is a big supporter of my self-exploits..
I send her pics all the time and links to vids I've posted online. It really turns me on that this activity turns her on so much. Especially since it turns my wife off completely... I'm sure if I was single, I could easily hook up with this friend. She's already told me so to my face... Who knows what the future will bring..
" ....
I THINK THAT'S SUPER AWESOME. I hope you get a chance to selfsuck with that other woman sometime.
It's too bad your wife won't join in on the action. My wife will occasionally suck my cock with me, but she's not big into it. However, there's another girl that knows of my tricks and she said she'd be down with it, if I ever go to visit here. I'm hoping.
Anyways, this is a great subject and I'd love to hear more stories of people getting caught or showing their talents in a public setting.
