Do couples really have that much sex when they are younger?

Absolutely!
And yes, it gets less frequent the longer you're together :P

Yes!

Its that man again!!

Been married 14 years and we still do it like the first night we met on sept 21, 2000

Yes. Three to five times a day for the first few months.

The film is an exaggeration. Students who "make out" in public places usually are disciplined according to codes of conduct. But then, I am speaking about a few years back. But schools now seem even more controlling of personal behavior.

Depends on your personal preference, your active life and your choice of partner. Some folks only like once a day, others once a week, and some never at all!

Find a partner that fits you.

If you have the right chemistry and interest in bed activites, then yes! if not then no...its not about age at all...its all about finding a partner that like do the same stuff as you in bed and that you both feel attracted to each other ofc. But alot of people today take what they can get at first sight and doesnt even bother if the chemistry is there or not and they are doomed to have bad and boring sex for life.

~If the realistic details fails, the movie fails~

Yes
