Exposure to pornography before going out; will the relation of natural pheromone production attract men?

I majored in Biology & they've never proven a true pheromone system in humans. Men pick up on unconscious fertility cues that occur around the time of ovulation in women like your voice raises slightly & you're less turned off by chemicals found in men's sweat around the time you're fertile but sex chemicals released due to watching porn? - I don't think so. It's more likely to make you aroused before going out & as such you might be more likely to seek out male attention which could come across as desperate.
