There are different types of sexuality. I can't remember the term, but there are many people who prefer to have connection first before having sex (you know, the type of sexuality and romance usually depicted in movies). Others are promiscuous and don't mind casual sex.

People are just different. Some are promiscuous, others aren't. So long as both parties communicate what they are trying to achieve and have mutual consent, it's not really an issue.

I think the problem is that most of people don't realise there are different types of attraction/sexuality. We either assume one is promiscuous looking for body count, or looking for long lasting relationship. I didn't even know that there is a term for the type of sexuality/attraction I mentioned on the first paragraph. I always refer to it as "normal" because that's how I am expected to view dating and relationship growing up.
