Sexless 7 months

my boyfriend and i have been together for a little over 7 months and havent slept together.

I am a 24 y/o virgin woman. Partly we waited because of this, but now i am not sure why we are still waiting.

He hasnt wanted anything sexual in a few months. he used to feel me up and I went down on him for the last time a few months ago

I talked to him about it a few weeks ago and he said it was something we could work on together but nothing has changed. He also claims to not be a very sexual person.

Any reason why?
