Tony Abbott's opinions

Tony is entitled to his own opinions (about sex) -here. I think I agree with his "rules", but not his apparent idolising of virginity.

it is the greatest gift that you can give someone, the ultimate gift of giving and don't give it to someone lightly

Of course I maybe taking him out of context - like some other people.
It's also possible for people who weren't virgins to have a God honouring marriage.

I think my thinking and theology relating to this topic may well differ.
Of course, marriage is pointing to the greater reality of Christ and his bride, something much greater. And its our behaviour within marriage that helps point to this greater reality. (There is also the wedding dress if you catch my meaning - See Rev)
Well, back on Earth, I think our main problem with our attitude to sex is our selfishness -the other stuff are the symptoms.
For Christians its also trusting God's design for marriage.
