The only thing that ever makes sense is following your own heart. People's sexual preferences can change periodically, daily or hourly! Time and experience will reveal to you what you prefer, in the meantime, I wouldn't put yourself in a relationship with someone if you think they may repulse you at some point. When you find a PERSON you want to be with, their gentialia may not be as important as the feelings you have for them. Have fun being young!
