Partner's Low Libido?

Hey y'all! Just looking for a little advice from the gang.

So my boyfriend and I have been together for over a year and a half now and have been living together for several months.

I know sex drive goes down and fluctuates during long term relationships, but my partner's libido has been very low lately.

It seems like he only wants to mess around or get physical once a week, but the infrequency is not what is bothering me. The problem is I have a pretty high sex drive/openness to sex. I think the only time I have ever turned him down was once when I was 90% asleep.

He on the other hand doesn't seem to be interested in me at all. We will cuddle, but making out seems to affect him very little, and the hurtful thing is he always wants to go straight over to his computer and play videogames instead of messing around a little then playing them.

It hurts because I am easily aroused, and very attracted to him, but I don't feel he is reciprocating that, or feels the same way. He insists he does, but the string of actions seem to prove otherwise. I am totally fine with masturbating, but the sex isn't really about physical release, but rather a physical connection with my partner.

It simply feels like he doesn't want me.

Has anyone else experienced something like this? I have tried talking to him about it, but he feels as if I am bashing his hobby and like I should automatically know he is attracted to me, but I need a little reassurance.

If anyone has advice or knows about this sort of situation, I could really use some help.

Thanks guys.
