Great start on the icon. We like the idea of the hands joining and the heart adds to it. Not feeling the colors though. We're trying to get away from purple because we've always used it. We would like to see each M in the icon a different color like you have but somehow the feel of joining the colors for the heart and make the heart one color or a fade, etc. The idea being we're merging the make and female into one.
The font should be something a little fancier. We use Adobe Caslon Pro now so take a look at that because we like it. You don't have to use that one specifically but something more with the look of it.
We like #42 and #43, but not the ones with the icon on top as much.
The icon in #43 is nice because it would work great for an iPhone app.
As in our previous comment we would like to see a version of #42 with the heart either in one color or a merge (fade) of the two colors showing the two M's are coming together as one.
We don't really like the pink. We're trying to stay with colors that appeal to both men and women and feel the pink/turquoise is more feminine.
The subtle heart in #41 is very cool. Run with that idea as well.
