I think the only think you could gain by asking this of individual people is their own personal experiences and opinions. It would be very problematic to attempt to generalize that for the entire gay Christian population.
That being said, I'd like to point out that the Bible does not speak very clearly about the rules of heterosexual relationships. Not unless you think straight relationships are about polygamy and treating women like objects.
In general, gay people follow the same social norms as straight people. We meet, we date, we fall in love, we form committed relationships... or not. Everyone's different.
As far as sex, we tend to be more educated about human sexuality, if only for the fact that the rest of society insists on making that a big issue for us. I think gay people definitely have less hangups and anxieties about sex than a lot of straight people. Therefore, we are less likely to feel guilty about having it outside of a committed relationship.
And hey, if any of you fundies are uncomfortable with that, than maybe you should be encouraging gays to form committed, monogamous relationships. There's at least one great way to do this (starts with an M...)
But yeah, I would be really careful about trying to find universals in the attitudes and practices of either the straight or gay Christian populations, especially on a topic as huge as love and sex.
