It's great you're trying to break some social taboos and change society to be better for everyone! And it's also great you're learning English!

some American taboos are:

1) tattoos and piercing - especially visible. While this is becoming more popular, you're likely to get some stares if you are covered!

2) cutting in line - we like people to be polite!

3) not saying please & thank you - always expected when dining or doing anything that requires the person to be gracious.

4) eating with your mouth open!

5) talking loudly in a library or church

6) living with your parents after you are 25, unless you are taking care of them or you have faced financial trouble

7) getting pregnant before 18 (or even under 21) - especially outside of marriage ("out of wedlock") but, it's becoming more normal.

what are some taboos you have for men?
