On the EDIT PROFILE page, there is POSITION, where various positions are listed such as, top, bottom,...... including SIDE.

I think SIDES has not been well elaborated on this part;
There are sides who feel like they are submissive like how bottoms are in a gay relationship, let me call them SUBMISSIVE SIDES, and most likely such SIDES are looking for DORMINANT(toplike) SIDES.

And then there are SIDES who feel like they are the alpha male like how tops are in the relationship, let me call them DORMINANT SIDES, and most times such SIDES are looking for SUBMISSIVE(bottomlike) SIDES

Then there are sides who are VERSATILE, like how versatile people are in gay relationships and such sides are most likely looking for another SIDE who has the same feeling of VERSATILITY just like them.

Finally there are those sides who are BISEXUAL.
They can be:
Bisexual DORMINANT SIDE like tops
Bisexual SUBMISSIVE SIDE like bottoms
Bisexual VERSATILE SIDE like versatiles.

I hope you can go through my suggestion and perhaps make some changes so that everybody is well catered for, and also so that the confusion goes away on the issue of SIDES.
Also, it will help SIDES easily find partners.
