[Opinions] Stallion does have pretty strong sexual connotations (m)
In fact, it seems right on a level with Stud. You hear about Italian Stallions all the time. At least I have. Just as often, you hear about Stud Muffins.
I keep thinking I've heard of Stud being used as a first name. There's Studs Terkel the writer. But his name being plural makes me think more of jewlery and wall-studs than sex. lol
