Hey so I have been a sex worker, dominatrix, camgirl and been in porn. And the VAST MAJORITY of women in these fields aren't exactly spoilt for choice when it comes to work. It's not necessarily that the performers or workers are 'forced' in the conventional sense, but we are certainly forced by circumstance. Some women have kids and are single parents with no support, some are experiencing significant socioeconomic factors that make a well paying job almost impossible to get, and some still are in entrenched poverty cycles.
I'm not saying it's all adult entertainers, but it's the majority of female and trans workers. People generally don't aspire to be in adult entertainment, and a lot that say they do are lying to maintain a fantasy for the clientele.
