You’ve never seen a beautiful woman and had a quick thought? I have met men that have had thoughts about a man, and they are the furthest thing from homosexuals. Satan can throw thoughts at people! Be a Christian witness long enough and you will hear everything...
Let me try:
Heterosexual sex with someone who is not your spouse adultery. Lusting after someone of the opposite sex who is not your spouse also makes you guilty of adultery.
It is possible to recognize that someone is attractive and not lust after them and to have your mind made up in advance that even if an opportunity were to present itself you would not act upon it.
We all have a natural inclination to sin in some way, and all Christians do battle against sin. If someone recognizes their inclination to sin involves same-sex attraction, and they guard their thoughts and actions in order to avoid sinning, I wouldn’t call them homosexuals any more than I would call the straight person who guards their thoughts and actions an adulterer.
