I wouldnt go with dirty, Dirty on a man says I am a player and have been with another women. Unless your girl knows your using it she may pick up on that and then your not getting any LOL If she is aware your using pheromones give it a go but also I want to make you aware dirty smells like hell because of the copulins in the mix. You will defiantly need to cover it with a good cologne.
If I was you I would go with Turn Up The Heat. It makes you more aggressive and her more horny. I would use Instant Shine with it or Instant Honesty to temper it a bit.
One more thing when using pheromones around your girl keep in mind that she knows your natural pheromone signature and will have a delayed reaction or confused reaction at first. Read up on that in the forum. Be sure to start out with small amounts.
These two are a good start but there are alot more so you can learn to use the products to your best advantage.
