Nice guys/incels act like not having sex is a life-threatening condition. First off, yes, it's great, but there are times when it's more trouble than it's worth for a person. Secondly, are they aware that are whole groups of people who go their whole lives without having sex, by their own choice? People in some religious orders, people who are legit asexual for example.
Exactly! They need to realise that you can go without having sex/having a girlfriend and still be happy! Dating/sex should be a bonus to supplement a good life, not a need. And there are men who do go without sex (maybe not strictly their own choice) but dont act like whiny entitled bitches about it. Its human nature to obsess over what you dont/cant have or get rather than appreciating the good things that you have in your life
