on topic comment.. the week before my period i am the horniest human being to ever walk the planet. ever. my body is sorta demanding sex. and my brain is along for the ride.
during, the horny continues unabated. period sex and period orgasms are awesome. no cramps, the contractions speed the end of my period. regular orgasm before and during my period shorten it to about 48 hours. AWESOME!
dating women for most of my smex life cured me of any period sex squick long time back.
eta: what i have noticed with myself and partners.. the flow slows up/stops during sex.. for the most part the blood was already in the vaginal canal before sex, gets pumped out during sex.. but not much else. now, after sex, or a really strong orgasm.. totally different story. noticed, meself and me girlies, a pick up in flow rate.
not sure if this is typical.. period sex is not on my causal sex to do list :redface: so the action has been limited to partners or regular fuck buddies.
