What does 'fag' mean? What does "It's not a fag, darlin', you have to hold it in." mean?

"But you want to know how to really be great? How your Great
Lover really pleases a lady? Now, all your basic smoothie-type fellows
will always say they know, they're an authority and such. It's not a fag, darlin', you have to hold it in. Most of these fellows, they haven't got the first damn idea how to really please a lady."

Answer

There is not enough context to be sure. But fag can mean

1. homosexual (which it doesn't here) 
2. a cigarette  (you blow out cigarette smoke, but you hold in the smoke from marijuana )
3. a stick of wood
