Could anyone help out with this?

Hi, I think it's great that you are considering coming out to someone and this can feel scary but it's an important step to being comfortable with your authentic self and living your best life. If you feel your friend is possibly transphobic or homophobic, is there any way of testing that theory out? For example, perhaps you can mention you like a song by Sam Smith or someone else who clearly identifies as LGBTQ+. If your friend replies in a dismissive manner that maybe you are right. They may however just not be a fan of Sam Smith's music but they reply may help you feel more confident about your next step. The one thing I would say is life goes by so quickly and if your friend is homophobic or transphobic you will probably find that once you do come out to your friend and others in your life, your friendship will probably change and you may well feel disconnected. Surround yourself with friends who support you for who you are, who don't just accept you for being gay or having a less masculine voice but who love you for who you are and celebrate what makes you unique. Best of Luck, I really hope it all goes well for you! Ronan

You can't be certain of that, he/she might not be transphobic or homophobic, most people just dont admit openly...

But if you are coming out, you should first spend some time with the person and get to the person better...
Then when you are ready to come out, do it on text first, not face to face ..

Maybe try speaking loud and manly with heavy voice, it would eventually get thicker ... and speak calmy , not too fast
