I just feel like there'd be a significant difference between it happening naturally at puberty and a sudden 180 change overnight as an adult.
And I also think that as a gay man, you might have a different perspective on it than straight people would, since you've already had experience with questioning your sexuality and coming to terms with who you are. Someone who's always been the "norm" and never had to question themselves suddenly being met with something like this could be set to receive a bigger shock.
