I'm having a difficult time with this one, everytime I want to get away from the temptation I fall for it with my girlfriend. It's hard a "habit" to break because I hold sex as an act of love (I guess that's another notion I need to get rid of) and I do partake of it on a regular, if not daily, basis.
Just not sure what I can do to get out of it. I know by God's grace but the connection with my girlfriend and I is so much more immmediate than it is with God.
My problem is my stubborness and my pride that gets in the way of any real attempts to turn over to God. I guess I'm fighting bouts of unbelief and this new "harder" way of life. Maybe I need to take a sex addiction course...
Actually, you're on to a few things here, and have a lot of hard work ahead of you.
1. Sex is
and act of love - but it's an act of mature love, love that is committed, planted in firm foundation, and which has plenty of growth & history behind it. Those who use sex without this kind of mature commitment are either severely hurt when the relationship breaks down, or have divorced sex from its fundamental expression of loving commitment, or some combination of the two. This isn't just affirmed in the spiritual realm - it is also affirmed in the psychological realm; sex is more serious than most people would like to think of it, and for those who wish to use it most casually, it has become ultimately meaningless, divorced from love. There's a reason why even the most socially-permissive psychologists will still tell kids not to have sex before adulthood: the bonds formed beyond the physical level are difficult to deal with, and if the psyche isn't developed enough, it will lead to neurosis.
2. If you're continuing to have sex on a "regular, if not daily, basis" with a woman to whom you hold no formal commitment (let's be honest - dating is hardly a "commitment" in the grand scheme of things), then you do indeed run the risk of becoming addicted - and if that is or will be the case, then she will become a tool for the feeding of the addiction rather than a partner in life. You're already at high risk for this, not only because of the frequency, but because of your description of how you react to her:
"It's this natural reaction that I have once my girlfriend is around, we start making out and one things leads to another. That's the way it goes. I hate to use this as an excuse, but I can't help by how beautiful she looks."
"For me it's a deeper connection, which involves the cliche pillow talk, cuddling, caressing, expressing how beautiful and wonderful she is, etc etc."
3. People continue to think that sex is a tool for learning about the other person, growing closer to them, etc; it can be
all that, but it's dangerous to use it without first laying a more solid and deep relationship foundation. IMO you've fallen into a perception trap, especially indicated in your second quote above, when you say, "For me it's a deeper connection, which involves the cliche pillow talk, cuddling, caressing, expressing how beautiful and wonderful she is, etc etc." The deepest connection is in the soul; but that sort of connection takes years to cultivate.
Your relationship needs a lot more work before the physically intimate interaction will provide meaningful addition to it. What would happen if you went "cold turkey?" Would your relationship not suffer? Would it only be a minor setback? Would it be a near-catastrophic experience that would set your relationship back quite a bit? Or would it be the "endgame?" My guess is that you would answer yes to one of the latter two questions, not the former two.
4. In the end, it's hard for someone to honestly evaluate the strength of their relationship when the various emotional and hormonal elements of sexual activity are at play. For some people, that is why they have sex so early: make them "feel" like they're further along, more committed, etc. with the other person than they really are. In any case, it is only serving to cloud your judgment - would you think it's prudent if you were to choose to purchase a particular house when blindly drunk, or would you commit to the military while high as a kite? Why, then, would you evaluate your relationship with your girlfriend while under the influence of hormones and emotions? When we are charged with our greatest challenges, the Church directs us to two tools of decision-making and empowerment: prayer and fasting. Both of these can be done together, as a couple; but neither one can coexist well with a pre-marital sexual relationship.
If the two of you are committed to one another, then your relationship should stand the test of abstinence, distance, time, etc. If the relationship is not well-founded, but only appears to be strong because of the sexual relationship, then it's better you find out now than later after you've invested more time & heart into it.
"Pure gold fears no fire." If your relationship isn't purified by the fire of God's love for you, then it will be impure; but if you let the fire purify it, then it will be a most precious gold.
