Is onlyfans cheating?

If several years into your marriage you found out that your husband had searched for women he knew on only fans and subscribed to at least one woman in your city but it was only a year into your relationship before marriage, children and living together, what would you do? It still feels like a sense of betrayal to me.

Would your husband/significant other be okay with you sharing nudes with other men you knew. I feel like it’s the same thing.
