I haven't had a "bad orgasm" exactly, but once I think because we were rushing things a little, I got a headache from it. Its complicated but it has to do with too much blood rushing to your head from trying to reach an orgasm really quickly. That was my lesson early on to slow down lol. Haven't had it happen since which is a good thing

The tiny little orgasm I managed to eek out with the Eroscillator was just pathetic. That qualified as bad. It definitely put me in a grumpy mood.

I've had some pretty bad orgasms. I've had orgasms where they've barely managed to come (pun intended or not, you pick). I've had ones where my leg cramps up in the middle of it (this is ESPECIALLY fun). If I'm rushed (and it's not part of a kink scene... just the "oh yeah, come for me" when I'm already TRYING to come) I've had ones that were weak. Those are all "bad" in my opinion.

"Good" ones make me moan and sometimes will need to catch my breath...

"Amazing" ones make me yell and talk and whimper and need to catch my breath...

Multiples make me laugh and cry at the same time (and these always involve my g-spot)

I've never really had a truly "bad" orgasm, but I have had some that afterwards I felt like I might as well have not even bothered in the first place.

I've had orgasms that have given me bloody noses (usually when winter sets in and the air dries out.) Those are kind of a bummer, especially if your partner gets squicked out by blood, and you're not the first one to notice.

Other than that...

From PIV, anal, finger clit stim or dildos---some are weaker, some are stronger, some leave me speechless for minutes afterwards. But they're all good, even the weak ones.

From dedicated clit vibrators---while the orgasms can be just as strong as anything in the upper category, sometimes my clit will hurt a lot afterwards, and if I have something inside of me it will be really uncomfortable and I'll need it out. So while the orgasms themselves are just fine...the sensations afterward are bad enough that I would have rather gone without the orgasm sometimes. I don't know if I need better quality vibrations or what, exactly.

if we play for along time first ones geart,second ones good after that it like was that one

I can't recall ever thinking that after an orgasm. There are some that I would say are less satisfying than others (for me, pure clitoral orgasms are that way, much less satisfying), but I've never thought "that sucked". Now, when I was younger and didn't have orgasms... that truly sucked!

As an add on, I'll say this since it just popped in my head - sometimes, if I have a huge amazing orgasm, and I can tell I'll orgasm again, but the 2nd one is tiny and weak, I will think I should have just left well enough alone. lol I'll be left feeling less satisfied after the 2nd than if I would have stayed with the huge amazing one. But that's just my bad judgment call, and I've learned how to do better in that department so it doesn't happen much.

never had a "bad orgasm"

I've never experienced a bad orgasm!

I have while masturbating. Sometimes I know why (such as I went too fast or was too distracted) and other times the build up is fantastic and then, poof, the orgasm is lame.

OKAY, I just had the WORST ORGASM EVER a few nights ago. I was OMG HORNY and I jilled-off and I ended up hornier WAY hornier than I was before I jilled off. SOOOOOO DEPRESSING. I just went to sleep after that. It wasn't even worth trying again, my vibrator and dildo were packed and in the car and I couldn't get to them to try and help remedy the situation.

I thought all orgasms were good

Yes it happens to me, it is hard to explain but if I don't have a gush, I feel like I have been cheated.

Sometimes, when I'm getting close to orgasm, my left hip starts to hurt. Like, really hurt. I don't know just how things are wired, but it truly sucks when that happens. Doesn't stop me going forward, though.... it just means that if I was having sex with a partner, that's when they have to get off and just use their hands because I will need to almost close my legs to aleviate the pain. :/

Yeah, sometimes I get like 2 contractions that are almost nothing. Usually when I'm stressed and distracted. It's a total letdown.

Probably those from a vibrator that is really not strong enough. So bad it's almost pointless!

A bunch of my orgasms have been like that

I'm not sure if there can be a "bad orgasm", but there are definitely some that are much less satisfying. Combine that with a males' refractory period and there can definitely be a disappointing orgasm.

I've had them (twice) when there's an ejaculation but only a hint of the contractions. I was playing a long and then all of a sudden there was a single squirt or some dribbles and that was that. I was left thinking "what happened?"

The two times I've had them have been from anal/prostate stimulation. It sounds odd, but true: anal/prostate stimulation, which can give phenominal pant-and-rest-for-a-lo ng-time orgasms also have given me the disappointments. I guess that it must be the "milking" thing that gets talked about from time to time - enough of the right stimulation and pressure and the reproductive system just dumps the semen instead of giving you the stars-and-fireworks. As I've said it's been very rare, though, most orgasms are fun.

The other "semi-disappointments" are those where you're tired and just trying to get to the finish line.

I only get headaches after orgasm if my blood pressure is up.
