Older men!

I’m starting to have this wild fetish for older men... I spent my teen years dating men my age and it was horrible. Then one night I went out with my aunt and she introduced me to her long time friend. Lets call him RockBoy, he’s 33. I’m 20. I got a few drinks in me and ended up sleeping with him and oh my god it was a whole new experience. I then met a man who was 46 and I couldn’t keep my eyes off him. The sex was amazing and I can’t seem to get him out of my head. I’m so young, why do I get so excited over these men? Has this happened to anyone else?
