As opposed to the standard ORgasm, an andgasm is simultaneous climax achieved by both partners during intercourse. Particularly hard to time / pull off but immensely rewarding.
It wasn't until our 2nd month of going out that my girlfriend and I had our first andgasm

An intense rush of pleasure, similar to an orgasm. It is, however, not the result of sexual activity.
If I were to get a new car for my birthday, i would have an andgasm!
