I expect her to kiss me if I want after I lick her so yeah I do it. When I'm intimate with a new girl I make it a point to do it, I think a lot of them have been with guys that don't want to do it and that leaves them with mixed feelings about performing it, so I do it to let them know I appreciate it and I still find them desirable not "icky".
Besides if anything you got is too dirty for you to taste or have contact with I'm pretty sure you just made a case for why you shouldn't be getting blown in the first place.
