Perhaps Andreas no one has commented because your question itself is a bit ambiguous.
How do you define LOVE?
God loves you. God loves me and because of this I love you. I (as should you) love other people on this site, though I/we have not in any case met them.
From the context of the original question though, I think you mean can you (as a married man) have carnal desires (fulfilled or otherwise) for a member of the oposite sex to whom you are not married. I would answer that with a very definate NO.
Your question raises another question in my mind (and probably in the mind of all others who have read it) a question I do not want an answer to, but you should answer to yourself, Have you such desire for someone to whom you are not married? You must examine yourself carefully and (as Joseph Scriven says) take it to the Lord in prayer. His answer to the question, and to yourself, will then be quite clear.
