Im on a birth control that makes me have a light period, 2-4 days, and there isnt a time that we dont do it while on the rag, im very comfortable with it, he makes me feel so loved, and worries about my pleasure before his, spending an extra 1/2 hour touching me, kissing me, talking to me, which turns me on to the extreme!! After a shower, I even let him go down on me(I do have a tampon in) and after I cum, out comes the mouse and then its smooth sailing from there!

I would think, light or heavy period, to me it's just like a natural lubrication, the first few days it doesnt hurt at all, I do find that the last day, im way more sensitave, and even if my period is gone, it will come back for a day or 2 after i;ve started taking my next pill..kinda weird, but the doc said its normal, she explained it like this, "your cervix in the last day is busy closeing up, ringing out the blood, like a wash cloth soaked in water, so when you have penetration inside of you, because your turned on, it opens up the cervix again, letting more blood out, completly natual, just more sensitave, so instead have having his penis constantly in and out all the way, my man usually just keeps the head of penis in and out, so its not knocking at my inside door lol...I find it brings us closer together, he's so obsessed with my body, blood or no blood, he always says " you can always wash it off !!"

Good luck, but like alot of people said, if your not comfortable with it, then dont do it, maying try talking about it more with your partner, getting yourself on the same level as him/her and taking it from there
