    Wireless Cheater 1

    Careful ladies. This one has genital warts and does not disclose before whether protected or not. He'll try to convince you not to bcuz rubbers are too uncomfortable for him. Watch out!! He's had since his early 20s and has probably infected the high hundreds of women he's been with. Do not send nude pics or let him take video during sex bcuz you'll find it on a revenge site if you anger him, reject him, or otherwise hurt his narcissistic image of being perfect.
