as a straight male, i would consider dating a MTF if i found her attractive. considering how rare it is for a transexual to actually end up looking the slightest bit feminine, it probably won't happen. but i would consider it, even though i do think that they're most likely going to have a host of other psychological baggage to deal with...
however, i was under the impression that a majority of MTFs post-transition go on to have relationships with lesbian women, any info on that?
