Y'all wtf is up with my boyfriend?! I can't make him cum no matter how long I'm down there.

I've gone down on 3 other guys in my life and I was able to get all of them to finish in a few minutes.

Now, with my current boyfriend I can NEVER get him to finish 😒

I used to love going down on a guy and now I honestly don't even like it because I can't get the job done...what do I do??
