@hearkat I’m exactly the same way. My breast tenderness usually is accompanied with my nipples being super sensitive, so having them played with them turns me on more so than usual. I switched birth control from the shot (which made my boobs smaller) to the patch (which can make them bigger, I won’t know until I stop it (because I’m assuming they’re getting bigger from being off the shot)). My boobs are going back to normal size/slightly bigger, so they’ve been super tender lately.
I have talked to my husband about having sex while I’m on the last few days of my period (I usually flow heavy/normal for the first 2–3 days, and then spot the rest, so there really isn’t much blood to worry about). He said he could try it so long as he wears a condom. I can only think of two ways it might affect me. 1) It might hurt more. 2) It might help with my cramps (which are incredibly painful, and I double over every 4 hours, right on the dot, when the ibuprofen wears off). We haven’t had a chance to try it before because I didn’t have periods when I was on the shot.
I think it might be relevant for the girls posting here to mention what birth control they are on if they are on any at all. Some of them can worsen menstrual cramps, so it might have an affect on how sex during periods feel.
