It is really great to see such an enthusiastic article on the topic of period sex. It is one of those things that never really gets talked about, or if it is mentioned, it is immediately negative and stigmatized.
But really, what does period sex come down to: yes or no. And that yes or no comes from the woman who is menstruating. If she is into it, why not? If you get into it too, then all the better.
Personally speaking, it is neither a significant turn-on nor a turn-off. To me it is still just sex. We just try to keep a towel handy.
