Am i insane for thinking my 19f boyfriend 18m may be loosing attraction/not listening to me?

Okay for a bit of backstory me and my boyfriend have been dating for about 6 months as of writing this post. And both parties are bisexual.

At the start of the relationship he was very attentive and very conscious of my needs however as of late some problems have arrose in the relationship based on that it is very clingy and we both spend far too much time together and that there are problems in regards to S\*x being about his needs and him completely ignoring my own.

I personally have sexual trauma and my boyfriend does not. My bf has been trying very hard to initiate s\*x when im not ready for it and will not do foreplay. Everytime i bring up that i need more fore play he says he will do it next time and doesn't. As well as thing my bf insists on me being ontop even though i feel absolutely nothing when i do so. I still do it for his enjoyment but now its all we do when i comes to s\*x.

When we tried to have s\*x last we tried doing a different position where he was on top and he stopped me and refused to carry on.

As well as this whenever hes been drunk hes been obsessive talking about one of our guy friends and flirting with them. I told him this made me uncomfortable but he hasnt stopped.

Im aware he that hes not listening when i try to communicate and i also feel as though his apologies arent genuine and he only hears what he wants to hear.

I don't really want to break up with him but i feel like these issues are too big to ignore.
