When I first tried m2m it was mutual sucking, and when we came neither of us swallowed. Personally I was afraid of having a guy cum in my mouth, although I did enjoy sucking and watching a guy shoot. So one day I finally decided to let him cum in my mouth, and I swallowed. Haven't looked back since. Have discovered that there are different tastes and volumes. Hooked up with a smoker and his load was DISGUSTING! No more of that thanks. Have a married regular I service and his taste is kinda neutral I guess, but not a lot of volume. I also used to eat my own before prostate removal so I guess eating cum is like drinking Scotch whiskey, it's an acquired taste, lol.
