Have you ever given your boyfriend a quick hand job because you didn't have the time to have sex?

Kind of opposite. My girlfriend would give me a hand job because she wasn't horny when I was. Then suddenly ask me to finish doggy style. I assumed she got horny enough.

After a couple of times I told her that she feels different inside when this happens.

Then she told me that it's not that she gets horny, it's just that her arm gets tired. I then had to tell her I'd rather just stop, than fuck her when she's not horny.
