Well, the only time my dick is pushed out of her “Va-jay-jay” is after I cum, stay inside, and go limp, and she orgasms plenty, so I cannot say I know this “shoved out” feeling.
On a side note, 60x a night? I find it hard to count after a while, but that is great you can.
Ladies? Feel free to chime in on the “shoved out” thing – I got nothing.
