Doing what he likes and wants seems to be more important to me

I love my soon to be husband very much.In my past (before him) it was all about me meaning the guy wasnt gonna get anything until i got mine until he made me cum until he made sure that i was satisfied.Well things change obviously especially after you decide settle down i mean highschool i didnt care what i did as long as i was havin fun doin but i settled down several months after i graduated.Now im with this man who is so amazing and treats me like no other guy has ever treated me before. The point of this story is i find my self doing more for him sexually and even nonsexually but the thing is i dont think it bothers me.Is that because he may actually be the first one i truly love? He is my 2nd long term relationship but i just have feelings for him that i have never experienced before and i have never cared this much for a guy and did as much as do for him for a guy in my entire life and to be honest im scared just because of the fact that i have never loved or cared for a guy this much and this hard. I mean as far as sexual things go anything he asks for he gets even if its before i get anything i know i go down on him everyday if not everyday then every other day but it dont taste bad so it dont bother me to do it but what do yall think about this? After goin through alot of guys through highschool and only one other long term relationship could this be the first time im actually in love instead of being a heartless dont care about love or feelings seducing tease? Im not saying this is bad or anything but man it sure is a drastic change and different lifestyle.
