Relationships

Could he be using me? Or am I overthinking?

I am F17 (turning 18 in a week), my boyfriend is M18. We met 2 years ago and tomorrow marks our 1 year of being together. (by the way I am the date-to-marry type, please get my concern)

I won't say he's a horrible boyfriend. Overall, he's an absolute green flag + really sweet and caring towards me, just like he was during the start of the relationship. But few things about him make me think maybe he's not the one.

His female friend: their closeness has caused a lot of tension between us lately. he said he'll reduce talking to her but not totally stop bcs of my suspicion based on my own doubts.
He sexts a lot: most of his texting points towards this topic even while im not in mood. there were episodes where he was forcing me to strip on vc. but realising this, he apologized later.
Dates: Everytime we go on a date, looking at him, it seems as if his purpose is to makeout. We haven't done much activities together other than this. I told about this concern and he said okay we can try exploring some activites but none as of now.
4: Doubt: I doubt that somewhere he's manipulating me into thinking that he asks for consent and doesn't force himself on me. He would keep insisting until I say yes.
He does check up on me often, pay for me at times and stuff like that but his activity lately has been concerning me. I do claim to love him back unconditionally, even if he would be at his lows but I am afraid maybe he's just a guy using me while I am choosing to ignore the signs unintentionally. I don't know if this post makes sense at this point.

Could he be using me? Or am I overthinking?
