Many of us have been there bro......the fear and unknown can be very strong.
Just make up your mind and go for it...this is what I did. That first time, I can still remember thinking in my head, "I'm actually taking my clothes off in front of another man...and feel myself getting hard as a rock.....and I'm not embarrassed or worried." In fact, it felt great. And then when I final touched his cock, kissed it, and began to suck his cock...I was in heaven. All the fear and uneasiness went away, replaced with a physical and emotional feeling of peace and pleasure. Sucking another man's cock felt like the most natural thing in the world---the taste and feel in my mouth was intoxicating......I now crave sucking cock.....
I went through a similar process with anal penetration....always knew the thought of being fucked turned me on I knew I wanted to try...so I finally tried it....and OMG...it is sooooo good. Just love it....best sex there is......Peace.
