How to handle my over-protective brother?

my brother (18) has a friend, and I really like his pal. His friend does too, and we've been together for a month. Suddenly, my brother told me that he did not like me getting 'sexual' with his friend. But a day later, my boyfriends love bite mark got my brother boiling with anger when he saw it. Now he wants me to either break up with my boyfriend, or he'd going to tell my mom!!! Please help...

I know it is difficult for a 18 yo girl in India. But try to tell your brother that he should deal with his own sexual actions and not yours. And that is just good if his close friend is that with who you make some cuddlings, because this guy will certainly respect you, as it is needed in your society. If he answers anything you may aswer that he may live his life without any cuddlings with a girl, but you are not so fish-blooded like he is. Between bothers and sisters it would be more interesting to tell each others's experiences in this respenct than lurking and sniffing, and being hostile.
