I remember reading a post from Spoiled Princess and Bbucko stating that a person who is a bad sex partner is usually an indication that he/she is bad relationship material from the get go - a sign to stay away. It is rather intriguing because it has been my experience that this is very true also. Selfish lovers are often turn out to be selfish pig headed partners. Needy in the sack, needy in real life. Romantic tender lovers tend to be conscientious partners. Can you usually can judge a persons temperment and tenderness by how they make love and is it a pretty acurate reflection of how they are going to be outside the sack? I realize this is very simplistic and there certainly are other factors that determine a successful relationship but it certainly would be interesting to see what other people's experiences have been.
