Fantasy problem..

What’s wrong with me? I swear when I was younger i was so much more hornier than I am now. My boyfriend has asked me about my fancies and I’m just lame like “I like it when you chock me, spank me, and pull my hair” and he has like dreams about us that are his fantasies. Idk what I lost, my like sex drive going through puberty or something changed in my mind during the trials I went through during my teen years. 🤷🏼‍♀️ I know it’s a long shot, but any advice or similarities out there?
