Does my coworker like me or am I delusional?

My coworker has never shown interest outwardly. However he does things that get me thinking. I said I was cold and he gave me his jacket, it could honestly just be a kind gesture but I was wondering. He also sprays his perfume on his neck and he asks me to smell his neck and let him know if it smells good. That could have been a genuine question. He always touches my head and hair just to tease me and he even gives me massages at time. I was also using the work computer and he just towered over me and used the computer he gets too close to me at times. I don't know i could be overthinking it but i am just interested to know if his behaviour is normal? Also i don’t get bothered by anything he does like we are chill.
