No, there was defnintiley some gayness insinuated. I found a quote of the dialog:

Bobbi Sanfillipo: Why the big secret?
Corrado 'Junior' Soprano: About what?
Bobbi Sanfillipo: Oral sex. What's so terrible about pleasing a woman?
Corrado 'Junior' Soprano: You always have to talk about everything.
Bobbi Sanfillipo: Well, I wanna know why.
Corrado 'Junior' Soprano: It's complicated.
Bobbi Sanfillipo: Yeah, but why?
Corrado 'Junior' Soprano: Why? Because they think if you suck pussy you'll suck anything.
Bobbi Sanfillipo: Oh, you're kidding.
Corrado 'Junior' Soprano: It's a sign of weakness and possibly a sign that you're a finook.
Bobbi Sanfillipo: [chuckles] A fag? That's ridiculous. How would the two even translate?
Corrado 'Junior' Soprano: What are ya gonna do? I mean, I don't make the rules.
