Be careful with that, man. I don't trust a lot of dudes out there. Gangbangs can get out of control.
Gangbangs aren't my thing so much, but everyone has their kink. I'm more into sharing an intimate evening with a M/F couple, whatever it leads to.
My big fantasy is impregnation/showing off my big dick -- but I have no intention of getting a woman pregnant in real life -- just pure fantasy.
(I've been boning up around pregnant women since I first started shooting my wad. LOL.)
Another thing I noticed lately, is that so many dudes are into MFM. FFM used to be the thing, but now -- if you're a well-hung stud, you get bombarded with dudes wanting you give it to their women. I guess it's no surprise: straight porn is full of big dicks, so ... the big dick visual is a big turn-on for most dudes.
