F23 I found out that my mom used to pay for her apartment with her mouth when she was young

I have a wonderful mother, she's 43, but she looks great and takes care of herself, basically like many women her age in Moscow (yes, she had plastic surgery on her boobs too), and she still works as a doctor and teaches at a medical college. We have a fairly friendly relationship, she raised me as a friend from childhood and shared a lot with me. And now that she's divorced, she's starting various romantic relationships all over again, and a lot of her sex life has been revealed to me ahahhhh (a lot has fallen into place, an apple from an apple tree), but sometimes I'm shocked by her opinions and experiences. In particular, she told me that she doesn't consider paying with "her body" to be something reprehensible for a woman in certain cases lol. Naturally, I asked, "What were you doing, woman???" It turns out that at 18 she was literally paying for her apartment like that. She was a poor student, and you see, "if the payback is just a blowjob, it doesn't count at all." I'm shocked by her, some pleasant, some not, but with her permission I decided to publish this story to get your opinion, and maybe to accumulate more questions for her in the AMA format, she promised to answer everything in detail ahahh
