Looking for some reassurance!
I've had a terrible history with boyfriends and dating. I've had previous relationships where I have been hit, controlled and worse. I've also had a previous "relationship" in which the (much older) man stole money off me over a prolonged period of time, which I never got back.
I've always had poor taste in men, I am a people pleaser as well so always end up not being able to stand up for myself, and just "cater" to their needs.
I was sexually assaulted as a teenager, and through therapy recently I have learned that my hypersexuality may a result of trying to take ownership of what happened to me. I am really ashamed of my past sexual history and, it sounds really sad and pathetic to say, but I've never had sex with someone where it was "making love" (if you know what I mean).
So I recently have been dating a guy who is completely the opposite to the other men. Genuine and extremely polite/respectful. We've been getting to know each other for quite some time now, and no one conversation has entered into sex talk/suggestive stuff, beside an odd comment like "you're beautiful" or "you look really lovely in the picture you uploaded today" - just nice. This sounds very normal I know, but to me, it's never happened before.
I feel like we've got a lot in common, and the chemistry is amazing. Again, not based on sexual chemistry (although I am very attracted to him) - something just "clicks", I've felt like I've known him for ages. He has said similar to me as well. We've kissed and hugged a lot and we're very physically intimate, but not yet had sex.
The only problem is that he lives about 2 hours from me, and so drives down to see me. Logistically it's difficult because we usually end up overrunning dates and he has to drive home around 5am in the morning.
We were messaging today and he mentioned that he would like to see me this weekend, and that he would book a hotel for himself so he didn't have to travel home. I replied in passing "oh you're welcome to stay at mine if you would like?" he said that he "didn't know about that, i don't mind getting a hotel".
I don't know why but his reply has kind of made me feel embarrassed? I wasn't even suggesting that we would have sex, but now all these thoughts are coming into my head that he thinks I'm easy and somehow knows about my sordid past 
I know his reply isn't nasty in the slightest- he's just a gentleman. But, I just feel so rejected and disgusting. I don't even know what to reply without sounding defensive. I have a tendency to get very defensive and cut people off if I think they think badly of me.
I need some help on how to rectify this, I don't want to lose him, but I already feel not worthy.
