I have a question about physical chemistry, which everyone says is important in any relationship, but which I don't experience at all with my boyfriend. We have been together for almost a year, and I really like him a lot. We enjoy spending time with each other, but I don't sense this spark or magic that everyone says one should feel with one's partner. I don't know how to fix it if I don't even know what is missing. Please tell me what I can do.

Why are you basing what your relationship ought to feel like on what everyone says it should? If the two of you like being with each other, love and respect each other, and feel as if you are both good for each other, why worry about a mythical spark that probably occurs more on awful romantic comedies than anywhere else? Magic can be mundane, and still be life changing. Don't look for problems that don't exist. That elusive spark will make its presence felt in time.
