when u jack off do u let for semen fly and then clean up(if so what do u clean up with) or do you put something like a towel down and jack over that?

I'm usually laying on my bed jerkin and I'll just let it fly, and clean it up with a shirt. Occasionaly, I'll wear a shirt, or have it on top of me, so my cum spooges right on to it for easy cleanup.

let it fly!

i think it's cool to watch your jizz

I just let the cum fly, and clean myself up with a wash cloth and baby wipes.

Mongoose - Did you really say "Baby Wipes?"

I use rubbers a lot for jackin. I like the look and feel of a rubber on my dick. When I'm jackin bareback, I lay on my back, pull it up and shoot on my belly. Then I use baby wipes and a cloth or hand towel for cleanup too. (Baby wipes are moist and are convenient to keep by the bed. Right by the box of rubbers.)

My cum hasn't 'flown' in a long time. It more or less does little spurts and runs down my cock/hand/masturbation sleeve.

.......I would suggest collecting your semen in a cup and after a while, when your ejaculation hormones subside, drinking it. I have been doing this for about a year and now really look forward to my next cup full. It tastes according to what you have been eating. But the taste is always good if not great. Some if it may be the psychology of it all. It's just neat to have your penis valued for the stuff that it was designed to deliver.

The few times [and I mean few] that my wife has allowed me to cum on her tits, I enjoyed licking her tits clean of my cum.

I almost always shoot into kleenex.. not one for the sticky clean up

Same goes for me!

I usually just cum into a sock but sometimes ill let it fly then clean it up with a sock after.

....Sometimes you can collect the semen in a small container and use it as a lubricant for the next stroking session. It seems to make for a more intense session.
....assanti

I just lay a towel across my stomach.

I usually use a Kleenex.
