Period sex

One Time my partner wanted to have sex because I guess every time I talk or look at him or even touch him he gets horny so I just started my period and it was light and he was like I need you I was like I’m on my period he said he was goin to put down a towel so it won’t get on the sheets we started to do it I wasn’t into like I usually I’m because the thought of being on my period turned me off and so I told him to get off of me and I had a whole panic attack
