30 [M4M] Nashville - I’m married, but can’t stop thinking about being a submissive cocksucker. Help?

I could really use someone to talk about this with, maybe like an online therapist. I’m straight, and have only ever been with women. I enjoy sex with my wife. But oftentimes when I’m alone and stressed out, I find my sexual fantasies drifting to me being on my knees, sucking a big dick. Even worse, I’m very submissive in theee fantasies, doing whatever the other guy wants while I get called dirty names.

The details change. Sometimes it’s a friend, sometimes it’s a stranger. Sometimes older, sometimes younger. I’ve tried to resist these thoughts, but giving in and masturbating seems to be the only way to get temporary relief.

I can’t figure out what my issue is. I’m wondering if there’s anyone wiser and more intelligent out there who can help me work through these issues and reach a satisfying conclusion. If nothing else, some support would be nice, like a therapy type situation. Hope to hear from you
