No no no no no no no...
You can have love. Buddha said don't obsess over it and hang your self-worth on anything. Own your own self-worth. So, if relationships come, that's fine, but if they go, let them go. Don't attach to them and obsess over them because if you do, you'll be unhappy. If you can genuinely let things come and go in your life and not get tripped up by them, that's fine. Sensual pleasure comes, it comes; it goes, it goes. Buddhism would encourage you not to fixate upon it. AVOIDING IT, like your OP suggests, would be a form of fixation, just in the other direction. This is why Buddhism is called the Middle Way. You neither pursue nor avoid pleasure and pain, but accept them and move on. (I'm not criticizing you at all, btw.)
There's a book called Open to Desire by...argh...google it. I believe it addresses this topic. Jack Kornfield, John Kabat-Zinn, Trudy Goodman, Bonnie What'sherface, they all are married or have significant others. The issue for a Buddhist isn't whether or not to get married, but what type of relationship to form to that person and how the nature of that relationship may interfere with other responsibilities and priorities you might have (like saving all beings from suffering, but that's not an issue you raised in your OP).
Cheers.
