There's no denial that one's gender orientation is certainly a core characteristic of any person, but it's not the only one.

Same-gender attraction did not exist in the pre-earth life and neither will it exist in the next life. It is a circumstance that for whatever reason or reasons seems to apply right now in mortality, in this nano-second of our eternal existence.

Any opportunity to serve in the Church is a blessing.

There are numbers of different types of partnerships or pairings that may exist in society that aren't same-gender sexual relationships that provide for some right that we have no objection to. All that said... there may be on occasion some specific rights that we would be concerned about being granted to those in a same-gender relationship. Adoption is one that comes to mind, simply because that is a right which has been historically, doctrinally associated so closely with marriage and family.

It really is true the Lord's way is to love the sinner while condemning the sin. That is to say we continue to open our homes and our hearts and our arms to our children, but that need not be with approval of their lifestyle. Neither does it mean we need to be constantly telling them that their lifestyle is inappropriate. An even bigger error is now to become defensive of the child, because that neither helps the child nor helps the parent. That course of action, which experience teaches, is almost certainly to lead both away from the Lord's way.

Merely having inclinations does not disqualify one for any aspect of Church participation or membership, except possibly marriage. But even that, in the fullness of life as we understand it through the doctrines of the restored gospel, eventually can become possible.

Either there is marriage as it is now defined and as defined by the Lord, or there is what could thus be described as genderless marriage. The latter is abhorrent to God, who, as we've been discussing, Himself described what marriage is - between a man and a woman.
