Unless that ass is seriously tight and round (and I'm not talking just so-so), no, I would not hit that.
Not gonna lie, I've hit worse, but that was back when any non-sloppy vagina - 18 or over - was fair game. Now that I'm older, I have to be more selective.
I don't want to waste what few good years I have left bangin' girls who look like groupies for MD.
