Boyfriend/ girlfriend relationships, where in virginity hops up.
Don't worry, I'll make sure to moderate this closely. 
Oh okay cool
lemme take part too
first, the line between a best friend of the opposite gender and a gf/bf is a
very thin one. Best friend being of the opposite gender is not impossible, but i see on most cases one of the two always end up having feelings, be it from the beginning or later on, feelings are eventually there one way or another; too many friendships i have seen being ruined because of this, its too awkward, and sometimes the one who is liked might agree to dating just for the sake of the fear of losing that person (again, i've seen to many of those, and not a single one worked out properly)
bf/gf relationships i do not oppose, provided the two people involved are mature and responsible enough. in general, i would say that by the age of 16 true feelings towards someone can develop. however, one must always be careful. Regardless of age, a heart shattering will take long to heal, if it ever does.
i am not discussing religion, i just want to point out to the fact that the 2 major religions of the world, Christianity and Islam, both prohibit premarital sex while Hinduism and Buddhism both "heavily discourage" it, and i think thats enough to make it clear that no unwed couple should ever have premarital sex. however even if this was not the case, one needs to remember that the physical sensation they get out of sex, is deemed worthless, not so valuable when it is given up so easily. virginity is something that when is gone, it will never be back. why give it up for someone who is not your "true love"? if she/he is your "true love" then why are you not getting married? be it legal or religious marriage, marriage, being legal or sacred is the one and only way of sealing a relationship.
