I've seen quite a lot of tentacle porn, especially when it comes to anime or hentai videos. To me, it can be a bit funny, gross, or sort of interesting but sometimes some of the actual tentacle porn is just not something I want to watch. There are some nice hentai tentacle porn videos out there that don't make me squeamish, as I have watched a few out of sheer curiosity. What does make me gross out is anything to do with an actual.. cephalopod. No thank you!
