Thanks for the advice.

I definitely think the "take it slow" advice is good. I still have this huge mental barrier about even entertaining the idea with her

On one hand, I want her to be able to fully explore her sexuality and be satisfied. If I'd suggested something similar to her, I'd want her to at least consider it.

On the other, I feel like even discussing this idea with her will forever change the dynamic of our relationship.

I guess I think about myself as fairly alpha. I've been out with her and had situations where I've had to chase guys away from her (e.g. I came back from having a smoke and there were a couple of douches trying to hit on her) and I guess she's always liked that. I am worried that by entertaining the idea of cuckolding myself, that she'll view me as less as a protector.

I guess at this point I'm having hypothetical arguments with myself, and the smart move is so explain all this to her. I just don't want her to think that by talking to her about this that I'm any less of a "man"
