If how you feel about your body isn't mental, then nothing is.The notion that this is a mental problem and not physical unfortunately it’s totally erroneous. What is therapy going to do or what can you fix, nothing. At the end of the day the situation remains the same, Still not long enough and thick enough to reach and feel of the place or spots that she ultimately would prefer and no I’m out of therapy or happy pills it’s going to change that
What you can fix is the notion that penis size is the be-all end-all of sex. That you can't please a woman without a big penis.
You can learn that the places women get pleasure aren't eight inches in...they're at the first few inches. You can learn to be a great lover regardless of penis size or even having or using a penis.
At the end of the day, keep being miserable, negative and unhappy with yourself. Don't listen to a guy with a big cock who tells you, from a life's worth of experiences, that it means nothing. Keep hoping for what won't happen because it can't, instead of living to the best of your current potential. It's YOUR life, not mine, so live it or be miserable, your choice.
