Sorry, JacktS, butt I don't think that will fly, either. Any woman, solo or with a partner of either sex, can exercise whatever with any *toy* imaginable, simulating any manner of sexual relation. What about all of those hetero women who bought the "Buns of Steel" videotape!*bg*
Besides which, I know from experience as a bi-sexual, that plenty of lesbians and bi's have their hearts broken, when they find out the person they fancy is hetero. One can't always tell whether someone is gay, hetero, lesbian, bi, or anything in between. Trying to define sexual preference by body shape is just silly.
