I really liked sucking cock and tasting cum from other guy's dicks before I met my wife.

She knows I like it, but doesn't want me to do it (she says its cheating - which I agree with her, so I don't do it).

But i still think about it alot. And i fantasize about what it would be like to have a female partner who was OK with that, let me explore it more, maybe try MMF threesomes and let me clean her up after she gets fucked. Or even let me suck a dick every now and then.

I say let not because I am sub, I don't want to be a cuck, humiliated etc. I guess its more a stag and vixen thing...but I respect and trust my partner and would never cheat, hence the wording let...which is more like mutual open relationship kind of thing.
