In some percentage, also, the facial expression in men is lesser than in women.
But, there is another side of a coin.
This also can be different in some cases, for example I gesticulate with my face far LESS than both genders, and yes, it is very very confusing.
Especially because I do not want to move my face so much just because another person would 'like it' ( they actually say that to me) or they feel 'more conformable' if I do ( they say that too).
It is also very strange to explain that it makes ME uneasy and makes ME feel very unnatural.
In fact I feel like a moron.
So far I met a few people who are the same , they gesticulate less with a face but more with the words and body, and there was no objections whatsoever.
One of these people is my husband and he is of a rare kind that has a happy face the whole day.
