hey, we spoke about this earlier
and yes, people can be gay at any age, as you long as you know it's genuine, and it's not just a phase
but yes, it's definitly possible, and if you really dont feel atracted towards females, then yes, your either Asexual (however your atracted to men) or gay.
bit blunt, but thats how it is
and coming out, well coming out to close friends is the first thing to do in my opinion, and your parents, well, we tallked about the lil stories earlier (

) but it's whenever the time is right
and of course it'll be scary, but it's better to let it out at the right time, then have them figure it out for themselves
but it's whenever the time is right
well i hope the above helped
just gimme a yell if theres anything else, feel free to send me a message
