Gay is not accepted completely in my society

Im 18 years old and I'm sure I will never come out to anyone because I've already heard opinions and reactions about gays from close friends, even my family, so I don't ever think of coming out to anyone which will damage the attitude towards me. Thus, I act very straight, like talk about women with my straight friends and that stuff I always desire having someone who can understand me and discuss in open minded about the ideology of being gay... I have so many straight friends, but being gay isn't my choice and I find myself always thinking about it. I'm also sure that nobody suspects my sexuality that I'm gay because i act very straight, but I always feel the social limitation and the inability like straight people. Do you feel the same way, like you were born with this limitation and you have to deal with it reality? I would be glad and thankful to hear thoughts, thanks.
