I think it's the people who are old enough to understand that find this argument is similar to moon and cheese. Just because he lacks a public girlfriend doesn't mean he's gay.
Why should it even suggest that he is. His position requires discretion and a certain understanding of "keep your mouth shut" from the people he dates.
When a wife suspects her husband has been cheating it's because she actually knows him well enough to catch his subtle signs. She is intimately involved in his life. I've been there and you "just know" because you know that person's expressions, moods, routine, voice, et al. I personally don't have the luxury of knowing Guillaume well enough to catch any subtle signs like that.
Sure, there are rumors about it but there are also just as many rumors that Felix is a raging womanizing playboy and he's been in solid respectable relationships for years now. There are also rumors that Guillaume, contrary to being gay or a hermit, spends a little
too much time in the club scene enjoying the company of female admirers. Are all the rumors true?
I think the question everyone is asking those who have a "feeling" that he's gay is what do you base that "feeling" on? Is it because rumors of 3 girlfriends and photographs of him with 1 of them isn't a enough or is it a prickly 6th sense sort of feeling (I'm not disparaging people who get "feelings" of that nature).
I have a feeling that Guillaume is a raging heterosexual who learned the valuable lesson of keeping his head down and his mouth shut when he was at Durham with Pia.
Every royal bachelor has had his sexuality questioned: Charles, Guillaume, Haakon-Magnus, Felipe, Frederik, Albert, Philippe, et al...Everyone was fully convinced that Prince Pieter-Christiaan of Orange-Nassau was gay. It was like no one even questioned it. He's now married with 2 children. It was discussed endlessly that had he decided to come out that he would have enjoyed the support of his family and the vast majority of the Dutch people.
