I continue as normal with my lover, why not? Just need to wash up afterwards and take sensible steps putting down old sheets, towels etc on the bed. In fact my lover is horny as hell during her period and needs - and gets- a good hard fucking. With my wife, different, she doesn't like penetration then, so I bring her off other ways and get a good bj in return. Other women I've had, it varies. But again last year I had the most amazing time with a woman in the final stages of her period. Not too much mess, but boy she fucked like it was her last day, saying afterwards that she always felt really hot this time of the month. But her husband was right off screwing during that time. Having a longer/wider cock than him helped as well of course!
