Fiance told me I’m not very “creative” in bed

The other day me (25) and my fiance (27) were having a lighthearted conversation about our past relationships. I was joking around with him about his exes’ personalities, their habits he found weird, etc. I confidently asked, again in a lighthearted manner, who he enjoyed sex the most with. I asked this because I was pretty sure that he would say me due to the addition of the emotional connection we share that he hasn’t with his exes. Keep in mind that he’s had 7 other sexual partners and he was my first, but again, I really thought he was going to to say me because of how much he has said he enjoys it. He paused for a second before answering and named his two exes before me and said that it was just “different” with them because they were “more creative” but only because they had more experienced themselves. He followed it up with reassurance that he prefers it with me because he knows I haven’t been sexually actively with anyone else. I asked the question so I have to be okay with the response and his honesty. I just feel pretty embarrassed and a little like the wind was knocked out of my sails because now I can’t help but think of that comment whenever we are intimate. Anyone have some feedback? I take responsibility for asking the question and I don’t resent him for it, so please leave that out of the comments. It’s more of an internal battle than anything.
