It is only a sin if you act on it - in thought or deed.

Read the article. It is worth the time to digest the totality of this man’s experience.
Is My Same-Sex Attraction a Sin?
Once we truly understand something is a sin, we can repent and ask for forgiveness. But if we think it is just bad judgment, or the way we are made, it is NOT a SIN and we won’t repent.
‘There is forgiveness of sins for all who repent.’
Jas 1:14 But each one is tempted when he is drawn away by his own desires and enticed.
Jas 1:15 Then, when desire has conceived, it gives birth to sin; and sin, when it is full-grown, brings forth death.
Aren't our "own desires" coupled with enticement the same as "attraction"?
The root of the problem is the DESIRE. We have to ask God to remove our desire. A bible based solution to remove desire:
1Ti 5:1 Do not rebuke an older man, but exhort him as a father, younger men as brothers,
1Ti 5:2 older women as mothers, younger women as sisters, with all purity.
Look on men as brothers and fathers, women as sisters and mothers. Nobody in their right mind would say it's normal and natural to be sexually attracted to your sister, brother, mother or father even for a little bit. Because to entertain that desire at all leads to sin.
Right you are.
