fainting during sex

my husband and I are newlyweds. we've been married for 6 months. we didn't have sex until we got married, we've been together a year total.

Monday while we were having sex I fainted 😱 this has happened 3 times. the first time my husband thought he killed me. my husband is very big, 11.5 inches to be exact. yes I measured it. he is very gentle with me in beginning then get rough just a Lil. I'm thinking about seeing a doctor about this.

my husband says it has happened before with his ex girlfriend but It really scares me.

have anyone else ever had this to happen? please share

rude comments will be reported. never a troll that's why I don't share on here. I never said his size was the cause that's why Im seeing a doctor. smh
