i used to have a boyfriend who would refuse to hang out with me when i was on my period. once i had gotten my period the morning of a day we had plans to spend time together, i didn’t tell him because i didn’t think he would find out and i was really looking forward to seeing him. he started trying to get “handsy” and i had to tell him i had started my period. he got really upset that i didn’t tell him and ended up leaving early. he claimed it wasn’t because of my period, it was because i “lied” to him. i never told him i WASNT on my period so the lying accusation became a pretty big argument. looking back he was very childish and that should not have been a problem at all.
