I voted 'No' but this really depends on how you define a "good" christian and is more down to my radical opinions on sex. As an self-conscious atheist, I've still felt the impact of religious beliefs on my sexuality (I'm bisexual) as I went to a primary school with a Christian 'ethos'. Religion has some heavily and implicit anti-sex bias and this caused me psychological problems. I had no idea that these ideas were still affecting me about 20 years later because they were so deeply buried in my unconscious. In my experience, the brain just doesn't "work" the way the bible would want it to. So I hope my input is not unwelcome.
The more literalistic, fundamentalist interpretation of 'good' as derived from observing god's commandments will definitely be a no. An much more open, reasoned Christianity that gives greater grounds for interpretation and gives the individual has greater authority to interpret the meaning of the text could give you a yes. However, it will end up being logically inconsistent because even if you say homosexuality is 'ok' and not a sin, religious generally reduces sex to procreation within the sanctity of marriage rather than the pleasure of the experience.
So, you may find a loophole, but it won't give you the freedom, peace of mind or satisfaction you deserve. Gods love should be unconditional, but he is asking people to repress a natural drive to express their sexuality; both heterosexuals and homosexuals. A fair number of hetrosexuals have homosexual feelings or experiences (but don't identify as bisexual or seek same-sex relations). the psychology of sexual desire lacks the distinct boundaries between gay/straight and in marriage/outside of marriage that a religious text may require. hence it is probably safer not to accept an authority to determine what is right for you.
