Rick Berman would never sanction an openly gay character on any of the 4 shows he worked on, but he can totally support displaying a teenage boy fetish fantasy of having two women kiss. Mirror Ezri and the Intendant Kira. Intendant Kira was always portrayed to swing both ways, even with herself (Prime Kira) creepy as that is. Intendant was always wearing tight form fitting leather, and Mirror Ezri sports black leather cloths. Only thing you're missing is whips, chains and nipple tassels.
That don't do enough to ease your pain. Trot over to VOY for the scantly clad 7 of 9 and the subtle and sometimes not so subtle relationship she has with Janeway.
