Sex During Cycle

ok so i know your period isn’t anything to be ashamed of but like it’s gross to me i hate the sight of my own period blood.

but the other day me and this guy i’ve been talking to we’re making out and things got pretty heated. now i told him i was on my period but he didn’t mind so we did it the first time he came fast and the second time he didn’t cum at all bc he got a sight of the blood and wanted to stop.. now does anyone else find it weird to have sex on their period or is it just me?
