I love my boyfriend but he seems to get upset with me whenever I don’t want to have sex. We’ve been together for almost a year, my periods are quite irregular and most times I bleed more than the average person due to a medical condition (3 weeks to almost a month). I know during that time he wants sex but I always please him in other ways. We’ve had sex on my period a few times but it’s very painful. He knows this and stops if I get uncomfortable. He’s pretty understanding for the most part but some nights I can tell he’s mad at me, even though he claims he’s okay.
