Anna David has a major misunderstanding of what defines male homosexuality. If a man is attracted to women only, regardless of where his erogenous zones are, he's heterosexual. The only way he's bisexual or homosexual is if he is attracted to men. It may be useful to note that the most common sexual practice among gay men is fellatio, yet nobody would consider a man receiving oral sex from a woman as a homosexual act. Neither would anyone consider a woman who desires oral sex from her male lover an indication of latent lesbian desires. Enjoying stimulation of any particular part of the body has absolutely nothing to do with sexual orientation, and it's really sad that there's so much shame and confusion about what people enjoy with their partners and how even the "sexually liberated" (e.g., Anna David) continue to have hang-ups about it.
