Hey There,
From what you have said and based on others experiences on the forum I would say that the top two on your shopping list would probably be Instant Openess and Honesty so that he will open up a little more and tell you what he really feels. The womens guide has info on the various pheros available to you but perhaps if you add a little Instant Sexiness to the mix that could also help.
I’m sure that some people more versed in the female phero world will be along soon to help you out.
Good Luck!
