Advice!

I've been in a lgbt relationship with another guy for about 2 years now. I'm constantly hor** and have always put sex on the table but he always says no his not ready. I don't know what to do?? Like for a year we used to always make out and do the basics kissing and wa** together and stuff but even thats stopped now. I've asked him if his lost interest in me but constantly tells me how much he loves me.

if he says no he may have his own reasons

I completely understand and have always tried talking about it with him but its like his uncomfortable and just tried to move on from the topic. He did mention in the past his scared of the pain and etc but he wants me to be the dominant one in the relationship and has always labelled himself as "Bottom"
