Relationship problems

I am a cis female. My boyfriend is transgender. Him and I have been together for 6 months and we fell very fast for each other. The other part of this is he is healed from bottom surgery and so I was ultimately his first. In the beginning we were really good and we had really good times together. Ever since though he and I were intimate that’s all he can think about and talk about. Literally all day every day and it makes me feel somewhat like I’m being used Like I’m being used as an experience and not having the same intentions as I have. Yes sex is important and attraction is not an issue AT ALL. Like there have been times where I have made plans for us go to do something with friends and he wants me to change my mind cause he wants to stay home try different things and ditch the plans. I feel like I’m being used as an experience and nothing more.
