I thought the present-day standard position among people who have actually thought about the issue rather than just repeating stereotypes is that men don’t actually feel less emotions than women—they just show less emotions, for fear of being seen as feminine.
There is also a difference in which emotions are felt by (statistical) males vs females and even difference in which felt emotions the statistical males will show when felt.
