Don't enjoy sex with boyfriend...

It feels horrible to even write this but I don't enjoy sex with my boyfriend anymore... we've been together for 5.5 years and our relationship is great but our sex life... idk.

He's made me finish once during our entire relationship. I've faked the rest bc I don't want to tell him how difficult it is to make me cum. Now, whenever he wants sex, it just feels like a chore. I can barely even get wet or in the mood. It's rare when I'm the one initiating. I started a new birth control and I feel like that killed my sex drive even more, to the point where I just never feel like it now.

Idk what to do... I love him so much and slightly dread when he initiates bc I basically have to pretend I'm enjoying it... I feel like such a bitch...
