My girlfriend was actually willing to have sex with me while i was on my period (We’re in a distance rel. and i was leaving in a few days) only we did it in the shower, but the fact I was so paranoid about it being gross kinda made it hard, but once you get past that it’s actually quite good ~

Exactly. The only thing that was holding you back was your fear of your partner being squicked out! When, in fact, you both were okay with it and you enjoyed yourself once you let yourself relax.

Shower sex when on your period is ideal because it’s far less messy and no worries about cleaning up after!
