If you're interested, a survey of trans women revealed an orientation split of about 23% straight, 31% bisexual, 29% lesbian, 7% queer, 7% asexual, 2% other.
Off the top of my head, I know that Heather is strictly into guys, Joanna, Tristan I believe? and maybe ZoeM? Basically, look for the young transitioners, those who transitioned in their teens and twenties. They are statistically more likely to be into guys, where older transitioners are more likely to be lesbian or bi.
I'm bisexual myself, so I'm just rattling off the names of people I know who I think are into guys.
