Hi Tantine.
I cross checked with the dictionary. 'Stud' is a slang term for man regarded as attractive. And 'ΠαιδάÏας' is also a slang Greek word for the same thing and it would only be used in a love context in a sweet/humorous manner. If you feel the word is too strong then 'Handsome' I think would fit.
The original definition for the word stud is a male horse used to inseminate female ones, so if the Greek word has the same type of sexual connotation, the word is fine. If not, it may be a bit too strong.
Having said that, "handsome" seems a bit week if it is in a sweet/humorous context.
I'll set a poll with "stud" and see what our other Greek speakers think.
