Is period sex gross?

As A guy it happens to be my favorite time to have sex..it feels so good and is more intense..just have to clean up!

The answer to your question is going to be determined with what you consider gross! The sex itself feels great. The downside of course is that there will be a mess afterward to clean up. Good pre planning can help that. I have a big Ole beach towel I lay down on the bed so other than us cleaning ourselves up, just throw the towel in the washer, clean, put away for next adventure of this sort. I sometimes have terrible cramps when my auntie flo is around and I have found for whatever reason the sex relaxes the pain.

CAUTION; Don't do as one of my girlfriends did, get so involved with your guy that she failed to remove her tampon before he entered her. Two things happened (1) Said she never felt pain like that before in her life and (2) when his d*** went in so did the string and they managed to get it out, but you can guess how that went.

Apparently when you have sex with your periods, its meant to feel a lot better.
i have done it once, and it was OK.
mind you I wasn't bleeding heavy so there wasn't that much mess.

I've never had it either but it does not sound like it would be pleasant.

Not really during. But afterward, my boyfriend was a little disturbed, and said he felt like he had raped me. Hah.
