Here's my exchange with my wife from Monday:
10:29 Her: I have old bag aerobics tonight btw

(she's been in an aerobics class where she's the youngest by a generation)
10:30 Me: Were you saying this is the last one
10:30 Her: Yea
10:31 Me: Poor you with no exercise next week.
10:39 Her: If you can, I am out of <something>
Note here, I sent my response at 10:31 and while I had somewhere for the conversation to go, I did not make myself appear needy by asking her why she stopped responding. I waited for her next response at 10:39. And I'm not saying what she wanted me to pick up at the store. It wasn't sexual. It's relevant to later conversation though, so let's say it's a product women need.
10:44 Me: Does this have anything to do with the naked aerobics i was going to offer you next week? Of course I can, I don't even remember the last time you had to buy that on your own :P
See what I did there... I had to think about it a few minutes, but I picked up the conversation where I was meaning to take it before. I still responded to her question, and I did it all playfully.
11:03 Her: Yeah true

11:05 Me: What can I say, you have a nice &@%!! I want to take care of it
(I was driving, and the text to speech translator on the phone actually put in those symbols for the word I said - I thought it was funny)
11:08 Her: Naked aerobics like in natiional lampoons.. when theywere in France LOL
11:12 Me: You naughty dirty girl! Do you want me to pick you up for lunch and eat you out?
(I think this kind of sank in subconsciously because yesterday she really really had a craving for oral sex)
11:13 Her: No. gonna walk to McDonalds
11:15 Me: Want me to take you?
(Double entendre!)
11:17 Her: I need the exercise...u would have to be in work clothes too.
(See, her real meaning was she wants the exercise from walking to McDonalds, and if I joined her I'd have to wear clothes like I was at my job. She knew I was in shorts and t-shirt, and she works with her mom and we haven't told her mom I'm out of work.)
This one was full of potential double meaning in the context of the previous conversation. I knew what she was saying consciously, but I think her inner **** managed to slip it out in a way that was open to interpretation. I ran with it.
11:21 Me: Well I'll give you a workout but I didn't know you were into dressing up

I'll just eat my sandwich and save youfor later.
See, my vehicle is a full size truck and the gas is low, and moneys a little tight so I wasn't that set on driving to meet her for lunch.
11:29 Her: Oh.. ok.. U could come if u wanted
Holy libido driven subtext!!! I felt like if she was innocently and unintentionally using double meanings before, now she was flagrantly signalling back. At this point, I'd be an idiot not to take the invitation from her and join her for lunch. Even though she had no idea her subconscious was sending me these hidden signals, if I didn't join her for lunch her subconscious would have perceived me as rejecting her signals.
