Sexual Relationships 
Sexual Health 
(Trigger warning)
Men and women have different requirements, views and prefrences when it comes to sex, relationships and marriage.
Women are free to choose to have as many sexual partners as they please. Most men see the women they have casual sex with and the women they have LTR/marraige with differently, that's not an argument or analogy it's a choice that men make with their head and their heart. It's just like women being reluctant to get into an ltr with a guy who hasn't gotten his life together or has no future prospects. The key analogy "A key that can open many locks is a master key but lock that can be opened by many keys is a shitty lock". is more of a joke than anything but does hold some truth to how men view the women they sleep with or date long term.
When it comes to commited relationships most guys want women with low numbers of sexual partners preferably none and least around the same age or younger.
You might say this is hypocritical of most men as they are not likely virgin's or might not have low numbers themselves but I would say it's no different than of the requirements most women have of men such as
1. He must be 6ft even though most women aren't.
2. He most be financially stable even if she is not.
3. He must be sexually experienced and know his way around a woman's body even if she inexperienced or crap in bed.
4. Must be physically fit even if she is not
5. Must be good at at doing traditional male tasks such as car maintaince even if she can't boil an egg.
The lists goes on like that.
We have moved away from many traditional notions and values of how relationships should be but ultimately most people including the most feminists women still have a prefrence for traditional marraige and gender roles for men in relationships/marraige so it's only right that men should have a similar desire for women to preform their traditional gender roles in relationships/marraige.
Women still expect guys to:
Most modern women seem that when it comed to marraiage:
That low numbers virginity, (which was an absolute requirement for marriage throughout 99% of its history), is unimportant
That it is not a serious, lifetime commitment, but something you can try, and then cancel if you don’t like it, and the man may be obligated to give you money for months or years afterwards
That they can ride the cock carousel through college with no repercussions on the ability to pair bond later, and
That marriage will be all fun and games with no serious sacrifice.
I think I've rambled on a bit bit and im not much of a writer anyway though men and women are equal we are not the same and thus have different requirements from our partners when it comes to sex, relationships and marriage that may appear unfair to either sex. The old saying "men are from mars women are from Venus" seem to apply and we should accept our differences and celebrate those instead of shaming each other for our prefrences and choices.
