Is visiting a gloryhole a good base to starting manliness?
This is an interesting and surprising question mainly because it is coming from you. I am having a hard time trying to figure out if you are being serious or you are being just another Getbig asshole.
If this is a honest question, then my answer is that sometimes we do things we later regret. In my opinion, it is manly to admit doing dumb shit. Letting a stranger on the other side of a wall with a hole in it at a sex club get me off is no more egregious than someone letting a streetwalker suck them off in their car. Something which some Getbiggers brag about on a regular basis.
Think about this, many guys on Getbig literally boast about their seamy sexual conquests and it is all good among most of you...even when it is with a tranny, because somehow that's not gay.

Dave, you may be as pure as freshly fallen snow. More power to you...and I mean this sincerely. Many of us fuck up at some point or another. Most pretend it never happened, which makes all the others who did dumb shit feel like they are scum.
Stupid, stupid me. I thought being honest and admitting not being perfect was a good thing...like going to an AA or an NA meeting and testifying about having substance abuse issues. It helps others feel not so isolated and bad about their experiences and themselves.
Many Getbiggers are such total fucking hypocrites who are ready to damn others for anything they've done that they have issue with, while most likely they have done much worse things themselves.
One time, a long time ago, I let someone suck my dick through a 'glory hole' .....get over it!....grow up! People do dumb shit. So what. Nobody got hurt. Nobody died.
