Female alpha?

I have a serious question and its hard to ask and get into without explaining a lot of stuff.

I guess my question is - can a fag be in service to a female?

It might sound like a weird question but I guess I've been trying to figure out how I identify and exactly what I am.

My situation will probably seem pretty strange and idk maybe it is. I have a girlfriend. We've been together for about four years. We both identify as being mostly straight, but both had some same-sex experience when we got together.

We knew we were both open minded and liked to experiment and that's always been part of our sex life. Even in the first few months we explored other kinks and things, and she started to explore being dominant with me. It was something I enjoyed so was more than happy to do it.

We also involved other people. We went to swinger parties. We found girls and guys online.

She found that she really liked seeing me do stuff with other men, especially taking a submissive role, and I found that I really liked being watched by her when I was in that sort of situation.

We've leaned into that more and more heavily. And we now have three regular alphas (two are gay/bi, one is straight) who use me on a pretty regular basis. They use me exclusively, they don't do anything with her. She usually watches, but not always. But in my head, I'm doing it for her.

It hasn't become what we do exclusively, but I'd say more than 90% of the sex I have is submitting to alpha men.

You might be thinking that this is some kind of cuck situation, but I really don't feel like that's what it is. It's not like these men are 'replacing' me. She just really enjoys the dominance of being totally in control of what happens with my body, and I love serving her - and by extension submitting to men.

I just wondered if you'd come across this before, or if our situation is unique in any way.
