As a bisexual woman, I can't say I'd have sculptures of dicks lying around, but I have certainly not minded the ones attached to my lovers, nor the dildos I own that are fairly good approximations, and I've certainly seen some that I would call beautiful. Function matters more than form in this case anyway, and to me, the way they look is just a reminder of their sex-relevant function, and what bi or gay person doesn't want to be reminded of that? They are not in and of themselves yucky to behold. I don't really think of vaginas as something I'd display a sculpture of, either, but they can also be beautiful, and again, this has something to do with their function on behalf of the person owning / sharing them. In both cases they are hella fun and their form clearly serves their purpose.

I have occasionally heard a straight man comment that he didn't think dicks were attractive, but that's the only group-which-owns-the-part-in-question I've seen do so. The same way straight women occasionally comment about vaginas.
