if your having second thoughts i would say no dont do it

Never do this on a horny whim. When in doubt, first masturbate to a powerful orgasm, and only then decide if you want your face pics to be public. Always imagine that someone you know finds the pics. Will your confidence be up to that? Will it cause actual problems?

If you have what it takes, then by all means go ahead and experience the kick of being 'out there'. Tip: make sure your pics are of good quality, so you can really be proud of them once the people around you find them. I have done it, and I love it. I'm totally happy to be the man in e.g. this pic:

If you feel comfortable with it and you are aware of that if you picture is 3 seconds on the internet it will probably be forever there (other people saving your pic and reupload it somewhere else) then sure, go ahead
