Has much/anything been written comparing the orgasm to a ticklish feeling?

Okay, I saw a thread where several people talk about how their orgasms were a lot more "tickly" when they were younger. I'm not talking about tickling leading to an orgasm, I'm talking about the orgasm itself tickling. I've read or heard passing references comparing the orgasm to a tickle, but I'm wondering if there's more out there. I've also seen posts on here where, even into adulthood, some people's orgasms tickle so much that they actually laugh. So there is definitely a similarity between the two sensations, an orgasm and being tickled. It's just that few have the intensity of the lucky few I mentioned. If there's any community on the internet that might have insight into this it's this one. Thanks.

I'd like to hear the answers to these questions too!

I've read many stories (mostly of the fanfic variety rather than anything traditionally published) that compared arousal to a tickling sensation.

The warm tickle of arousal began to blossom in my stomach.
His touch sent a light, tickling pleasure along my spine.
My nerves were buzzing, each touch tickling my oversensitized skin and almost too much to bare.

I'm paraphrasing, but things like that nature. I've never read about an orgasm being compared to tickling, or had the comparison go very far.

All my tickle stories has an orgasm in it... so for me, tickling is sexual.
Have you ever tried laughing while you were having an orgasm? It's quite overpowering...
Maybe I'm biased, but I think there is a connection there.
