Well IF Jeremy does actually decide to experiment---Jeeves would probably be the best choice for a first time in uncharted waters. He has the experience, and he also cares about Jeremy himself--
so even though I don't see them doing any real relationships or anything long term, I can see Jeeves saying yes because he wants Jeremy, and I can see Jeremy thinking of Jeeves because he will take care of him and not hurt him. AND there won't be any extra talking about it outside of each other.
Jeremy is so young in all of this--that he will have lots of time to decide "who/what" is his type after he decides who he is.
I still don't know that Jeremy really will experiment, or that he really wants to know.
