Seriously, I dun think you are ready for a r/s. The way you
wrote reflects on the way you look at gals. Pls dun treat them like
they are some kind of goods or merchandise. If you dun even know
where your own heart wants, then its better not to break their
hearts.
If just for a moment of fun and desire, you tikum tikum pick one,
you'll end up hurting the other. Somemore, I think you may not be
ready to go into a serious r/s, then after a while, you'll breakup
with the one you chosed cos you keep thinking and comparing with
the other.
At least now you can still see them eye-2-eye as friends. Keep it
that way until you are sure what your heart wants.
