What's the male version of "hottie"?
Solution 1:
Merriam-Webster has a gender-free definition of "hottie:"
a physically attractive person.
A quick Google search on "he's a hottie" yields many results.
Solution 2:
Hunk is probably the word you are looking for
As per Collins dictionary, the definition of hunk is "a well-built, sexually attractive man"
Solution 3:
I would suggest using word stud, but it gives quite a virile connotation. Citing Merriam Webster 3,
Stud: [...] a young man: guy; especially: one who is virile and promiscuous.
Solution 4:
A specifically male version of hottie would be dreamboat.
The term fox is usually used in reference to a male, while foxy is the female version.
The term dish or dishy is most often used in reference to a male.
Each of these terms has been in use for some time and therefore may appear to be a bit dated today.
Solution 5:
(as others have stated) Hottie is not gender specific. However, if you wanted a more male specific version, stud might apply (however this is more antiquated)
