I keep on having flash backs

I was ten when it happened and I’m only just turning 14 now I was raped and abused mentally and physically for 2 years and at any point of the day I could get a flash back but I’m dating a boy who I love and we have been together for about 2 years I want to have sex with him but I’m just scared because of what has happened. And please don’t say you’re are to young or you can’t love someone at that age cause it won’t help
