Well it does cause your skin to produce a lot more oil than normal which in turn could make you produce more of an odor that's sexy to women.
The whole pheromone thing has gotten a rep for being mostly a myth but I'm not so sure. Odor is a BIG turn on for me. I'm definitely attracted to a guy if he smells good and I dont mean his cologne or shampoo or whatever, I mean him.
Having said all that we're majorly attracted to guys that are comfortable with themselves, confident but not cocky. If you feel better about yourself now its very likely that comes through in everything you do now.
