Goku being with any woman except his wife is pure fancope. Goku is naive, oblivious to romance, unconcerned with societal norms, and focused entirely on training and fighting. Goku would literally never be with anyone except someone he's contractually bound to.

Of course people will self insert into whoever the strongest or most important guy is. It's a power fantasy thing. That's why you see all of those crossover fics where he pounds the entire DxD cast or those betrayed fics where he leaves his "naggy wife".
