Why does my guy bestfriend gets horny around me?

Anonymous
I have known him for 6 years already. We become really close and we help each other a lots. Just recently, he acted so weird towards me. He asked me to sit next to him explaining him about the lessons like physics, and he took the chance to touch my calves, he caressed him lightly (I didn't know back then, I thought it was just something unintentional). And he repeated doing it, I asked him what's wrong, he answered frankly "there is always some sexual attraction between boy and girl even if they're close friend.", I told him I never think of this sort of thing with anyone or him. He smiled and still repeated it! I pinched him and pulled his octopus hands away. He wispered me sexily. (I got goosebumps). And just this afternoon, he kept touching my calves, my outer thigh, rub my rub, and he looked at me in the sexy way. I told him that no matter how many he does it, he won't turn me on or gets me horny, I pinched him again and pulled his hand away. He whispered to me sexily like 'are you shy?'. I told him that I'm not shy, since we're close friend and we're frank to each other from the start. He stared at my chest (my boobs are small), and his crotch gets hard, so he tried to reach for my calves again, I told him "Bastard, STOP." He said he's getting hard, he grabbed my hand and place it on his crotch and didn't get success because I pulled my hand away and I said 'stop messing around, stupid' and I came back to my lessons. He begged like 'help me, I'm getting so hard.' I just put on my headset and ignore him. He said to me frankly again! "I want to touch your boobs". He stared at my chest or something, and I place my hand and hide the showed chest. He said softly "Damn, you hide it!". Briefly, he would take every chance to touch me but he rarely successes in doing it. (My chest are quite flat).

Why does he he behave like this? It's just so sudden!
