Men lie so much

So I met this new guy through work and we hit it off pretty well. We start talking about things and he mentions it takes him awhile to finish if he even does. So we start getting into it later on like weeks later and I am giving him this mediocre blow job I mean I have braces now so I am not as good and sloppy as I used to be because I'm not about to rip his skin off. He finishes within 2 minutes. What the hell. Why not just be honest about it. So ladies have you ever been in this situation?
