I'm in my mid-twenties and I've always had more female friends than male friends. I was in 2 serious relationships (one 1,5 year long and the other one 3 years) and 4 or 5 small ones, but they can't really be called "relationships". I no longer keep in touch with a great majority of all the girls I've ever met.
But I did a lot of things with these female friends and exes: visiting restaurants, parks, cities, going abroad, etc. I know a lot of places that are worth a visit or things which are fun to do together because I was there or did those things with some other girl before. I don't really hide this.
I've been in multiple relationships now where I always have a hard time telling those stories or speaking about certain things, because to my girlfriends I always speak about other girls or, especially, my exes (just because I did more stuff with the exes, so they come up more often as an answer). My girlfriends sometimes feel like I am constantly comparing them to each other.
Usually, it goes like this: My girlfriend and I go somewhere together to someplace I know is fine. We talk and at one point in the conversation, sooner or later, this magical question appears: "Did you come here before?" or "Do you know this place?" or "How did you find this place?". Or we go to some new place and in the conversation, I mention a story where I experienced something similar but different in some aspects or totally different. The magic question comes again: "Who were you there with? Were you there alone?". I've never had a feeling that these questions were asked on purpose to test whether I'm a womanizer or something, rather out of pure curiosity, just like when two people are getting to know each other.
I fought long battles explaining that those girls don't matter to me, and I'm telling her about the place or thing because of the importance of it in this particular moment, and not because of the girl I was there with at that time.
Adding to that, whenever we talk about myself and my past, my exes may come up. An example: I can say that I like dancing and I danced ballroom dances for 2 years (which is quite obvious that I had to have a partner). Or (this is a big one) about something that I didn't like about an ex or generally speaking about women. I'm afraid that I can mention my exes in a more casual setting like "I'm glad that you're not like that one because she was always X and Y".
For my next relationship, how can I honestly address those kinds of questions without coming across like I'm always talking about my exes?
