Does anyone else think that Justin Bieber and Selena Gomez have gotten a little too lovey-dovey?

i recently became a fan of JB when his movie came out. He reminded me of my little brother, and he was just too cute. so, i joined "Bieberhood" online just for kicks. well, every five minutes it posts in my FB newsfeed with new pictures of him and selena, and, at first it was cute, but now its getting kind of gross... I mean, they couldn't keep their hands off each other on that little beach vacation! I mean, COULDN'T. now, i keep seeing all these "spotting" photos with her hand on his "high" thigh, and i just now saw a video where he was freaking molesting her feet... i mean, why are they calling so much attention to themselves?? they're what, 16, 17? and they act like they're 25! just recently she was supposedly preggo and i wouldn't doubt it, because they HAVE to be doing it to be all over each other! idk why this bothers me so much, but it's just kind of disturbing. maybe because its ALL the time in my newsfeed. i think i'm a little traumatized.
