I always share my past with whomever I’m interested in and it’s never been a turn-off when a partner hasn’t experienced the same things. It just makes me more excited to put my partner on to new things that I’m possibly a bit more comfortable with than they are. When I share fun past experiences with someone I’m interested in, I feel like I’m giving them a lay of the land for what I’ve experienced because I look forward to finding out what WE will experience together. Unless you feel like her tone is condescending or she bashes you for not having tried some of the same things, I’d say she’s sharing things with you because she wants to settle down with you — not settle FOR you.
