my Husbands turn on.... TMI

Kristina • Mama to 2 boys & 3 step kids
So my husband and I just got married April 10, 2017. We got back from our honeymoon this past weekend. Our sex life has been amazing. I can't complain about one thing. We are super open with each other, comfortable, kinky and even use toys. There really are no boundaries for either of us. At least none we have come to. 
The past few months I've noticed that his dirty talk has taken a different topic. A topic of "big dicks". He would start by asking me if his big dick pleases me. Of course, that's a yes. Then he will ask if I love big dicks in general and put the topic on any of my past experiences other than him. He's not trying to get info from my past, as he knows I'd tell him anything, he's actually turned on by it. At first, I would try to change the subject back to him and his "man power" but he would specifically change it back to someone else's. Eventually I went along with it because I saw how it turned him on and so it turned me on even more. Well, this past honeymoon week he got not specific with the topic. Wanting to know who's "big dick" I was thinking about, if it turned me on to think of someone else other than him, wanting to know details of the specific time (place, position, when, etc). Again, I went along with it. After we were done I asked him if he was ok. I wasn't sure if me going along with him would eventually bother him, the fact that he's basically coaching me to think about another man. He said it doesn't bother him, as it turns him on and in return turns me on. That it's just a mental thing to enhance the sex and he knows he pleases me on his own. I was okay with that. Well last night, it got pretty hot. To the point where he wanted a name of a man and wanted me to call out that name with I orgasmed. Honestly, probably the hottest sex we have had. His idea, turns him on, which in turn also turns me on. He never mentions my past or another man unless we are having sex. Last night he even brought up my lesbian experience, as he knows I've done that too. I think just the fact of me with someone else turns him on even though it's him pleasing me. I'm new to this, open to it, but still feeling weird about it. My first concern was whether he would be bothered by it after we were done but it seems to be clearly a sex thing for him. He never brings up him and his past, just me and mine along with details and how it felt, I guess making it into dirty talk. I hope I'm explaining it right lol.  Any other ladies with certain fetishes or have a SO with certain fetishes. Were you weirded out by it, turned on by it, not ok with it, warmed up to it??
