I found the following post very useful when it came to determining my first order. It is a mini compilation of the experiences of the ladies who use the various pheros. Perhaps you can browse through it and see if any of them may suit both your personality and the Mr Cutey you are interested in. =)
IS is a favorite of many ladies around here. It makes everyone happy!
I was also told that IO/IH will ease both of you (the wearer and people around you ) and help with communication/conversations.
