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.

Also not a prostitute, also heard them answer this before.

They often pick something that makes it clearly different. Like always use condom at work, never outside work. Maybe only the boyfriend gets anal. Or maybe only the boyfriend gets vagina.

Actually the condom thing was an issue mentioned in the news in my country. That is not a good strategy, especially if they get a new partner fairly often.
