Is he not interested anymore...

Me and my boyfriend used to be perfect together, intimacy was regular and we both really wanted other and couldn’t keep out hands off each other.

A couple months down the line and I feel like I’m always the one who has to insinuate and initiate sex, I give him loads of foreplay and I get nothing and then we just have sex and it’s over just as quick as it started. I’m starting to feel really unwanted and like he’s bored of me. Is he losing interest in me?
