That's kind of a weird statement and attitude. To say that your girlfriend would never refuse you. She could and it would be perfectly fine and she would still be your girlfriend. Again, dfk depends what it means for you. I don't know about anyone else but if my boyfriend's idea of dfk was like those I mentioned in a previous post, I would not hesitate to 'refuse' him.Your girlfriend would never refuse you fiv and dfk, and this is why the acronym gfe stands for, for an experience similar as you would have with your girlfriend.
Fiv also. Depends when and how. Just finger banging does absolutely zero. At the right moment and done right, Fiv is great.
You can't make statements about some services without the certainty that it means the same to everyone. Every woman is different, some more sensitive than others. Timing is also a factor. Some things feel good when you're turned on, but are not pleasant before then.
It's not a combo at McDonald's, it's someone's body and personal preference.
