Is sex really a big deal?

Holly • Single | 16 |
I'm 16 years old, and all of my friends have had sex. 
Some say they just got it over and done with and others tell me it's a big thing and it should be done with someone you love.
I've been single for 4 years now and don't really think I'll be getting serious with someone, so I need some serious advice.
Should I just go loose it or wait for the perfect time?
