My orgasms are definitely more intense the second, or third time around and the cum shots usually reflect that.
My favorite masturbation position is laying on my back, on my bed. I notice (love) that the cum from the second orgasm will shoot much higher into the air, maybe 10 - 12 inches from the tip of my penis, multiple times. Cumming the first time the sperm will shoot up 2-3 inches or so, but not get "airborne" like the second or third cum.
I really learned about the intensity of second orgasms with my last girlfriend. We would both like to fuck doggy style on the bed or floor and I would usually, at first, either cum inside her or pull out and shoot on her ass.
One night though, we were fucking and I came but wanted her body more (because she was dressed up so slutty for sex that night), I was still hard so I reinserted and mounted her again. I was thinking I'd just pump her a few more times, but we quickly got back into a rythm, and maybe 10-15 minutes later I could feel a second orgasm coming.
The second orgasm was absolutely wild! Up until then I had never come so fucking much in my entire life. It felt about 10 times more powerful than the first cum (which was great, don't get me wrong). But I shot cum uncontrollably, not only onto her ass, but up the entire length of her back, into her hair and onto her shoulders. It was fucking intense!
All she could say was "Oh my god! I didn't even know that was possible!". Needless to say, when we had sex after that she wouldn't let me quit after just one orgasm, she knew that if she fucked me real good she'd be getting two
We got to the point where I'd cum inside her and not ever pull out until I'd finished shooting my second load up inside her, minutes later.
Wow, just thinking about fucking her gets me hard... wish we were on better terms
In answer to your question though, no my second orgasms are most certainly MORE intense in every way!
