My ex's paid for everything. I find it constricting to consider conventional box-mindedness. We are all prostitutes selling our bodies, minds, labour, company for something to someone or other. quid pro quo.. I find it strange that "sex" is treated so differently to any other resource.. perhaps it is because it is usually highly restricted in order to maintain its power. Ho's effectively threaten the monopoly of "civvies" and offer a "cheaper" and easier way for a man of low social rank/dominance to "cheat"..
A man paying for or providing for a woman is considered perfectly fine. Often, sex is expected in return, under some agreed conditions no doubt.. We need no special laws regards such. Yet society imposes many, the most damaging being the marraige contrick.. Divorce payouts can often be calculated as being capable of showing how, in a case I know, a man may easily have paid pro-rata 1k plus per shag during his marraige.. Divorce, a likely consequence of the systematic abuse of males known as "marraige" costs us dearly as a society.. Many men commit suicide as a consequence.. Here is a danger to all.
Rarely do women every pay for or support men financially. when they do, it is not usually "just because they want sex".. Usually, they want attention, entertainment.. and yeah, a damned good seeing to from their man.. 
Marriage and divorce is a complicated creature. It's well documented in studies that women's earning suffer when having children, whilst men's actually benefit. So pay to acknowledge that if things breakdown is not unreasonable. After all they were half of the decision to have children so it would be unfair to expect the woman to carry all of the burden.
Outside of that. Well I've certainly dated men who want more emotional input and attention than I'm comfortable giving. But I admit I'm rare in that regards. Women do tend to put more in. There's a lot a talk about emotional labour with regards to relationships (part of why I'm not in one), that often falls predominantly on a woman. Also studies bare out despite women becoming greater contributors to earnings and doing similar working hours they still tend to have to do way more housework.
It's very much a bit of this and a bit of that. Rarely is anything equal.
You may view it as 1k in for a shag, but in one of my prior relationships I viewed it as making dinner, washing clothes, sorting his diary, remember his family and friends birthdays, etc etc etc. Plus paying for all his fun as I made more, even though still earning shit. Extremes exist on both ends. We all have to be careful not to view personal experiences as universal.
As for suicide, men are more likely to successfully do so as they have fewer warning signs, in part because society (including other men) discourage them talking about their emotions (and women do it as well. Which is awful). Which is a terrible shame. No one should feel like they can't voice their difficulties and resort to such an extreme. Rather than reaching out for help without judgement.
But divorce is viewed as one of the most stressful events in someone's life, male or female.
