Reading various things about this aspect of Dennis, he surely liked just about any girls/ women. Doesn't look choosy; ugly, beautiful, just nice-looking, pretty, cute - any girl could be to his liking, really.
Yes, Dennis even said as much once - I believe in Circus magazine. "Look, all women excite me for some dumb reason."
David Lee Roth (acknowledged fan of the BBs, and likely someone who considered Dennis as a role model) once said: "I don't get all the women I want, but I get all the women who want me." Seems this might also have been true in Dennis' case.
