Some guys can be physical without experiencing emotional connections. Others, however, prefer some level of emotional bonding before being intimate. Have you thought about where you lay on the spectrum?
Preferring emotions with sex doesn't make a person soft, weak or corny. Just as having sex without emotions doesn't make a person cold, selfish or insensitive. Labels aren't important. What's important is that you be understand how you handle sex. Part of doing that is being honest about the type of person you are and being open with your partner when you discuss sex. The best sex is balanced sex and being balanced means that both you and your partner are comfortable and knowledgeable about works best for both you and he.
When dealing with emotions and sex, it's best to be proactive. What I mean is, if you're looking for an emotional connection or want more than one night (even sub-consciously) and your partner doesn't, then the result can be disastrous. A strong physical connection may bring you together, but after sex, will either of you be able to satisfy the other? Make sure you're ready for the potential emotional outcome of sex and discuss what you're looking for ahead of time. That way, there's no confusion post action.
