Sex before Commitment, does S come before C?

In the Philippines, many people still adhere to conservatism wherein sex before marriage is unacceptable and in some extreme cases, lead to estrangement from their conservative families. I won’t be picking sides today since I myself is torn in between. It is normal for individuals to have sexual needs and inclinations, though acting on it is another thing.

I brought this issue up because I was having a discussion with a friend who will remain anonymous for private reasons. Our conversations led us to wondering, on when people started to put sex before commitment. In the normal course of ABC’s, C naturally comes before S, but with the case of younger generations, the order of letters have shifted differently.

If a guy asked you to have sex with him before committing to you in a relationship, what would you do? A natural reaction for Pinays raised in conservative families would be to think the guy wasn’t serious enough to commit to her first before asking for sex. Thus leading me to the our question,

How does one justify the need for sex before committing in a relationship?

Guy A told Girl A,

“How would you know if I was the one if you wont have sex with me first?“

I was confused with the logic behind the statement (if there is even one).

Does sex speak for the future of a persons commitment? So if a girl or guy was lousy in bed, does that mean he or she wasn’t willing to commit in a relationship?

Girl A is confused with Guy A‘s actions but she doesn’t give in. She wants the relationship and is ready for commitment, just not having sex yet. She’s dead set on staying a virgin until she gets married. Guy A keeps bugging her but she wont say, “Yes”, so he keeps her at bay, and contacts her every now and then to try and bait her into having sex with him before committing into the relationship.

Now tell me, if you were in my shoes, what advice would you tell Girl A?
