I like guys who like sports, exercise, music, and being social. Turn ons include confidence, intelligence, drive/ambition and a good bod never hurts.
Turn offs include guys that never stop talking, lisps, guys who are overly flamboyant, guys who think they are bi, dudes going nowhere in life/have no plan. I want someone who wants more for himself and pushes himself to get there. Oh... And guys over 25 wearing brands marketed to Tweens and teens (A&F, AE, Hollister).
