I'm no superman or anything, but for the most part, when I'm cumming, you best get out of the way, or get a shower of my cum lol! I'm a big time heavy cummer, my cock swells up even bigger and thicker, and then my balls tense up, and I'll have about ten seconds or just pure orgasmic bliss, and then I start streaming off load after load after load of my hot cumm, sometimes its more sometimes its less, but with me you can usually count on at least a good 6-8 rounds of my ammunition. Once while masturbating I shot a load that had an arc maybe going six feet high, and probably landed around 12 feet away, I shot across a room! Now I do not do this every time, but usually when I cum it is fairly intense, I'll often be shooting my load for up to what feels like forever but is probably closer to one minute if its a nice one. The first time I got road head, I was probably cumming for a good two minutes at least, I remember starting my orgasm on the highway, and finishing as I was pulling onto my street, and that is after exiting the freeway, waiting at two lights, going up a hill, and through my neighborhood... that was an amazing night lol!
But usually when I'm cumming it's inside my gf, she gets off nearly every time I cum inside of her, she loves the feeling of my load rocking her body and my pulsating cock, she orgasms from my first stream of cum 90% of the time. So I usually don't know how far I shoot.
There you go, long answer to a short question, but thats my style I guess.
