I don't think about being with guys while dressed or not; I'm in an LTR and very happy with a wonderful woman!
On the other hand, I'm more attracted to guys than girls and have dated men before. There isn't really a schism for me between halves of my personality. Whatever I'm wearing, I feel like I'm a woman, and who I'm attracted to doesn't change. On the other hand, I'm interested in straight men, and that doesn't work as well when you're not full-time or working with the right bits.
I'm not going to lead anyone on, but I want to feel like I have a connection with someone before anything intimate happens. So, in previous relationships I've waited four or more months until it gets to that level. Trust me, women are MUCH more okay with that than men, lol.
I guess the last thing would be that my standards are pretty high, not as far as being great looking, but as far as having their life together (good job, hopefully some education, good friends or family, happy and not bitter, etc.). Those are things I can bring to the table, and I don't want to settle for less. The long and the short of that is that women are way cooler with all of this. If anything, I've had ex gf's say they liked the soft skin and shaved legs, so who knows.
Frankly I consider myself hugely blessed to have found the person I have, who's sleeping in the next room, and knowing I get to spend Christmas with her. Whether you get it with men or women, I wish everyone to have that kind of twitterpated feeling.
