Bleeding during sex.. HELP

Hi guys, I need some help here. I’ve been experiencing bleeding during sex with my boyfriend frequently. It’s super embarrassing and makes me not want to have sex. I’m also starting to think he doesn’t want to have sex with me because of it. I just had my annual and everything’s normal and no STI’s. I usually have sex like once a week or every other week due to me and my boyfriends busy work schedules. Would having sex more often prevent this? I have had experiences where I didn’t bleed but it’s getting super old and annoying. Any suggestions/ideas as to why this Is occurring? My gyneo informed me to let her know if it continues and they’ll test cells in my uterus or cervix idk. I’m just getting tired of it and want to enjoy the intimate time with my boy friend😔
