Unrelated. I think you'll find that that was a temporary problem/unrelated. Masturbation is a good means of regaining your self-confidence. Plan for more foreplay with your partner - you've proven the equipment works; it's likely a matter of confidence & timing. Try something novel and exciting and you'll be gratified.
