This isn't the best advice IMO.

Of course, if you want to experience dating a variety of people, then go for it, you are young, and the majority of people who are in relationships at this age do end up breaking up... you will likely change a lot over the next 5 and 10 years.

Having said that, some people do meet "the one" when they were young and make it work. Long term relationships certainly don't have to be sexless, and monogamy doesn't have to be boring. Personally i would find going out and finding new D each night boring but each to their own.

From anecdotal experience, my ex from when i was your age has made numerous attempts and "confessions" that i was the "one who got away". Even married another girl, and he still had those feelings (unfortunately for him, they are not returned, he had his shot and blew it, and is getting a divorce).
