Honestly, want vs need is a conversation I have with children regularly. Worrying that some adults still haven't cracked it.
Yes it is sad that some people wont experience the joy of sex during their lifetime, there are many things lots of us would desire but dont have the opportunity to experience. Motherhood being one of them; but what do we do to tackle that? We provide treatment where possible, counselling, look into alternative options but even then many women have fulfilling lives without having a child. That should be the same for people that desire sex - treatment, counselling, alternatives (sex toys - not provision of a human.)
If you ever accept that there is a 'need' for sex, what precedent does that set? Where do you draw the line?
That disabled person needs sex, so lets provide it. That criminal needs sex, so lets provide it. Those incels need sex, so lets provide it. My husband needs sex, so I should provide it. I need sex, so my husband should provide it.
Its a ridiculous start to a downward spiral.
Humans are not a commodity and neither is consent.
There is no judgement on the women who are forced by circumstance or fear into prostitution - but there is judgement on those that buy into it.
