I've heard of one Tibetan Lama who refuses to give a traditional Buddhist wedding to h*m*sexuals. During the wedding he invokes some Buddha form in union and the bride meditates on the female Buddha while the groom - on the male Buddha. The Lama explained that he cannot tell where is the female and male element in a h*m*sexual relationship so it is not straightforward how to carry on the ritual. He received a detailed transmission from his teacher in a certain form and he doesn't want to alter it.
Although it doesn't answer your question directly, a few things should be said. Techniques involving working with energy channels are very advanced and usually were directly transmitted from teachers to students for centuries. It is rather dangerous to practise those without a guidance and protection from the guru, especially if the female/male energies are supposedly mixed as in the cases listed in the question. It is possible that although one Lama refused to alter the ritual, another one will be able to correctly identify energy channels and will willingly perform the 'individualized' ritual. Having said that, I don't think a general advice can be given. If one wants to practise some advanced technique, a qualified teacher is essential and only he can resolve the issues concerning the practice. The advice from the teacher is individual and should not be broadcast as it can only confuse other people rather than help them.
