That depends very much on the person.
A gay man is just as likely to have self esteem issues as much as a straight man, or a bi man.
Gay men are individuals who are attracted to other men romantically and/or sexually. Sexual orientation (being gay) does not influence someone's gender identity (being a man). Men, whether straight or gay, identify as male based on their self-perception and expression.

Gay men are already men.
Some do. Most don't actually. It is likely more to do with self-identity and gay culture than anything else.
It depends on how you define sex. If sex is defined as any genital contact for pleasure with another man the answer is somewhere between 1/3 and 1/2 of all adult men. This of course down't mean that these men are gay. In fact, something like 70% of men who self identify as gay have had sex with a woman at least once.
When women are gay, they are interested in other women. When men are gay, they are intersted in other men
Only straight men hate being called gay. Most gay men prefer the term "gay."
Gay men usually chase other men.
About 3.5% to 8% of men are gay. That is a small minority.
There is no odor particular to gay men.
Gay men do not dislike lesbians.
Gay men wear the same kinds of underwear as straight men.
