I'm not too sure what you're asking for.
At the end of the day, most people's attractions are based off their instinctual preferences. Some people mistake preferences with insecurities, that's a given.
If you're asking whether there are men who are attracted feminine qualities in other men ? yes, there are. I'm quite androgynous looking and often get mistaken for a girl and I also have a soft voice, or at least that's what I have been told. I tend to be shy, modest and subdued. Some men identify those qualities as feminine, some don't. I have been approached by men and usually they'd point out that its the more feminine qualities that they like about me that attracted them to me. I still haven't found one who I can trust, but that's another story.
I guess my point is that it is possible for gay/bi men to be attracted to feminine qualities in another man. Sure, not all gay men are and most will definately tell you that they prefer more masculine men, but that's just how it is.
For anyone who is insecure about this issue, please stop. It's possible, you just need to have an open mind, be comfortable with yourself and give it time. Don't chase people down the street with sexually charged innuendos or behaviour.
The people that you are looking for are out there, you just haven't met them yet.
