I can't help it. It is slightly unnerving to my boyfriend though. He has never seen this before. No, you are not doing anything wrong.
Many women laugh or even cry during or after orgasm.
Orgasm can release tremendous emotions during this time of enormous physical release. Orgasm is also a short period of time during which we are often at our most vulnerable. This can lead to all sorts of feelings rushing out. It is also possible that you are simply becoming enormously ticklish right after orgasm, which is very common for both men and women. Even the slightest touch can be downright uncomfortable due to this sensitivity.
