My boyfriend thinks I’m loose.

I also get dry pretty quick bc he takes his dick out and switches positions sooooo often. Is it possible I’m loose, or that his dick is just kinda small. He’s 5.5 inches and kind of skinny around. How can I be tighter/wetter ☹️ I’m so insecure about it and I hate feeling like he doesn’t like the sex 😔

I’ve faked orgasms before just to make him feel like he is doing something right, which yeah the sex feels good but just not good enough to make me cum.. I have no idea what to do
