Period sex thoughts

I have never had sex when aunt flow came to visit. Part of me thinks its gross but the other part of me says its natural. A womans period these days especially to men is taboo, gross, forbidden, an ultimate hell no.. but should it be that way. I decided to ask a close friend of mine how he felt about it. I put myself out there but ouch! It was not a pretty response. So here I am asking the glow community what their thoughts are instead.
