It's about penetration. Some Lesbians use strap-ons, though not all do. I mean is it really all that different from a finger aside from size? The penetration feels good. Doesn't mean that they want a man. I mean I'm sure a blowjob feels good, but I doubt straight guys would be okay with a man giving them a blowjob.
The whole tone of Church teaching in regard to woman is, to the last degree, contemptuous and degrading. - Elizabeth Cady Stanton
