Recently whilst me and my bf where just cuddling in bed we started play fighting which ended with him pinning me down - sounds sexual but I couldn't move and started having a panic attack. So I ask him again and again in a serious tone to get off and he doesn't for a good 5 minutes making me worse. He didn't understand that I was serious I don't think or that I was upset but now he realised he's done something wrong and wants an explanation (he feels crap that he's upset me). The truth is every close female friend/family member I have has been abused in some way by partners or randomly and the last guy I dated about one year ago forced me into stuff. I don't want my boyfriend to know this yet - we have only been seeing each other for a month and if I tell him he will become worried and then treat me differently because of it - which I get but... I don't want him to treat me like I could break at any moment because of it. Because I have spent the last year not dating and working though it, its just being in a relationship again, whilst I do really like this guy and care for him, and know he does really care for me and he would never hurt me intentionally, its scaring me. I feel pressured into things because it is the norm and don't know how to put the brakes on without hurting him or making him feel bad because he will feel like he is the problem when in truth he isn't. Any advice?
