I’m going to answer this based on what I have seen in London and I’m sure it will cause arguments and he’ll after that because this is LPSG.
He presents himself as straight, very likely is, and that is how I think he wants us to consider him. I’ve seen nothing to suggest he is exclusively gay at all. I’ve seen nothing to suggest he is exclusive when dating anyone.
In his earlier days in London, based on the people around him and who he attended particular events with at that time, he raised suspicions of being bicurious. Maybe he was naive since he just moved here. He has remained friends with some of that peer group, professionals, and sponsors and seems comfortable with notably gay friends. That is wonderful considering some of his views.
He’s been with a number of women, but I see nothing at all in him that suggests he is the marrying/domestic type. He’s very different from his brother Carlo.
Honestly, I’d rather bed some of his friends than him, but I can look at and enjoy him just the same despite his sexuality. A sexy body is sexy regardless of its label to me.
