Attractive married mormon girls

I am atheist that enjoys exploring different religions. I attended so many religious meetings and one that intrigue's me the most is the mormon church. There is no pastor, instead members talks. Some are also super friendly particularly the young men with black name tags. But what really intrigues me is why is that there are so many young families around. No idea, but I am assuming they are on their early 20s? And most of the wives are super attractive compared to their husbands who are mediocre in terms of looks. Is this a thing on the mormon church?
