I also felt the same but after some folks tried to convince me, I see it. Look, anybody can get sex. Even these "incels" are full of it. Any of them could go to a prostitute or eventually manage to sleep with someone at some party or what have you. Sex in and of itself is not the issue. What these poor bastards are missing and feel foolishly entitled to is an actual relationship. Someone they find attractive who loves them, wants them and will on top of that sleep with them. Sadly for them, their personalities are far too warped in an ugly direction for that to normally be possible, physical shortcomings aside. There are plenty of women who can and do fit this description where they have a toxic personality and are not conventionally that attractive or in shape and many unscrupulous men will sadly sleep with them, even feign true emotional connection with them but only be using them until they find someone better or until they're bored. Very overweight girls often fit this category, for instance.
