Wow not to sound like a slot but probably too many to count. Or at the very least let's say a whole lot, probably around a hundred or so. and that number is for people who have actually seen me in person. I do cam to cam jackoffs quite often and I've even posted videos of me and I even posted videos of me shooting cum on Xtube and xHamster, but the people who saw my videos weren't there in person, so don't really count. And when you say "Have seen you spurt your load" do you mean jacking off and ejaculating while they watch you shoot your semen or simply were present watching you have an orgasm? for example my ex-girlfriend who I use to fuck two or three times a day has seen me a have a hundred orgasms, but I was fucking her so when I came my load filled up her pussy so she didn't actually see my baby batter shootout. I am a heavy cummer so almost immediately withdrew my cock from her, globs of semen would gush out like a faucet and I would have to run and get a towel so she could wipe it up otherwise my sheets what have been soaked. So she definitely saw my semen, just not shooting out of my cock. Actually I did titty fuck her a few times and gave her a couple facials so I guess she has seen me shoot my load in that sense. most of the girls I hooked up with in college I would either have sex with or they would give me a blowjob and swallow my load. I've never actually masturbated and ejaculated for a girl, but I have mutually jacked off with plenty of guys since puberty where we both watched each other shoot are semen when we climaxed. I really enjoy jerking off with other guys even my fraternity buddies. I think it can be a great bonding experience and doesn't necessarily have to be gay or sexual. As long as you're both jacking off I think it's a great experience. I've never beat off in front of someone when they weren't jacking off as well. I think that would be kind of weird.
