I'll not speak for the christian gay community view, or even soulforce's view, I can only give my opinion. So here it is:
marriage is a civil contract, and as gay/lesbian, we do not have that luxury here in the US as well as in many other countries. I don't see "waiting for marriage" as an option for most in the LGBT community. That said, I don't think it's necessary to have the gov't's approval in order to express physical love for someone that you do, indeed, love. Many heterosexuals do not wait, many hetero christians do not wait. So perhaps we need to look elsewhere for guidelines. The commandment from Jesus to love on another seems to be the place to find that guidance. That however, does not give us license to have sex whenever, wherever, and with whomever we please. It's not about satisfying the lusts of the flesh. It is about honoring love between two people. If you are in a relationship, falling in love, and can make a commitment to each other, I see no reason to delay an honest expression of physical love.
