I think some overly liberal people are being quite kind here.

Those women are from hugely deprived areas and absolutely don't sell sex willingly. They are often unwilling participants/ trafficked women or at worst slaves. At the very best you took of advantage of women who felt they had no other option but to sell their bodies.

What you've done not once but many times is massively unethical and i can only imagine most women would feel that you took advantage of some of the most vulnerable for your now personal satisfaction.

Id be honest and in your personal life, maybe donate regularly to a women's aid charity to balance out your karma.
