Reminiscing my teenage years

Hello ladies I’m not sure if I’m alone in this but I recently been reminiscing so much in my young teenage years , especially sexually. I look at my old videos/pictures when I was 13-16 and get turned on to the fact I looked so young and was so active for that age, or look at my mans old pictures and know I seen him and his d*ck grow. I guess I feel this way since I’m still with the same man and engaged so I feel so connected to him and In love , we had never broken up, we are each others only partners and our sex life still amazing. We are living together now and having sex everyday just like we did when we were teens so it’s triggering me some flashbacks, back then we were attached to the hips just like we are now again. Also doesn’t help I recently had discovered old tapes we did on my old phone. The problem is I can’t stop mentioning it to my fiancé because I get off faster if I mention things we did when we were young, for example during sex we did something familiar and I mumbled out “I feel like I’m 14 again” and it helps me get off faster. Even when I want to get off to myself I have to think of my flashbacks when I was those ages. I’m wondering if this normal or I just feel grateful I’m still with the same man and I’m just in a nostalgia trip.
