I have a Question…….

Let’s say my wife did not want to have sex except once a month, even then it was me just licking her out then she fell asleep. The rest of the time she rebutted any approaches I made. Refusing even to help me relieve myself. If I then got My tablet out and watched porn and jerked off, and she didn’t like it asking me to stop but I kept going till I Blew, Is that sexual abuse?
