I've had a few partners that, during rowdy sex, have stuck a finger or two in my mouth like a fish hook while they get me from behind (and I'm so sorry for the weird terms, this is my first time posting about sex here, so I probably sound ridiculous and awkward).

Who is that for, me or him, and why? Am I supposed to suck on it? Bite it? If bite, are we looking for pain here? I kind of imagine it's supposed to be equal parts humiliation, restraint, pleasurable sensation (for him, another hole?), and pain (again for him, a bite?), but maybe he just saw it in a porn and thought it looked like a good idea :)

Does anyone have experience or insight into this? I have no problem asking my current partner, but out of curiosity I'd love to get your thoughts on this! Thanks everyone!
