Wife and I have been having plenty of sex over the last 12 years. She's always loved receiving oral sex, and I've gotten good at giving it, but I am not getting as much as I'd like and sometimes it's not part of foreplay at all. Never really made her have to wait for anything, and I know that can add certain tension and anticipation. I don't know exactly how to phrase a question, I think I'm looking for suggestions of how to express this to her without it coming off wrong. Anyway, I was thinking what I want to try to do is take turns, she has to give first - probably with a time limit like 5 minutes per turn or whatever, and if she gets me close I'll stop her and take her all the way to her orgasm. That's the basic idea.
