You cannot have sex without cum in your face. Either you receive your partner's semen over your face, or you begin sex with covered with cum. While guys still enjoy giving you a facial, you basically just wait for them being over and finally helping you out with your lower regions. Guys with only one shot rarely satisfy you, slightly depends on the body you have the day, so sometimes you need to get your cover first and explain this to your partner as some sort of foreplay you are into. Not everyone having their way with your lower regions is supposed to get onto your face. At least, some guys seem to be turned on and do much better satisfying you, after they fantasized about your face just being diped into fluids before.
Sometimes, when you stayed home the day, your partner always shots on your face. No matter how hard they try, in that case, they just cannot keep their semen, until they put their dick into your pussy. They cannot hold it and just come, shooting their first load over your face. Hope there is still something left for your date.
