Have you ever had any problems with facial hair?

Since February, I have had a beard (no sideburns or moustache). In the last few days though, I have had a lot of trouble trying to kiss my girlfriend without her laughing in the middle of it when it rubs against her. I’ve already told her its going, but just for interest sake, what might have changed? Has the presence of facial hair (on you or another person, this question isn’t only for the blokes) ever caused problems for you?
