Sex with aunt flow

So me and my boyfriend are hanging out tomorrow and obviously we gonna do the do but am I the only one who finds it so relieving to have intercourse while on your period it definitely helps the cramps. And the blood helps as a natural lubricant. Like Ik a lot of people say stay protected but me and my babe have been together for a year and we’ve been at the point of no return for a long time but might I say I feel no regret in having sex with my boyfriend and “aunt flow”
