LITTLE problem. he can't get me off.

So I've recently met this new guy and he's so so cute and suuuuper sweet and just like an ultimate dream guy. But we recently had sex for the first time and he's a lot smaller than what I'm used to. I didn't think it'd be much of a problem, but I've noticed I can't even feel anything... he's such such a sweet guy but could this be a deal breaker? I seriously adore this guy but it's kind of a let down. Help me. 😭 what would y'all do in this situation.
