I wouldn't recommend it. There is a member here named Bonnie Lo (I think that's spelled correct) who has a thread here regarding a kiss that resulted in a very unfortunate accident. You'll have to forgive me, I can't recall her screen name here. It has been a while since I've seen her post. If you find that thread link it to this thread if you don't mind. I'll look for it in the meantime.
That's right! Thank you Robin. Here is the thread I am referring to: http://geckoforums.net/showthread.php?t=31706 In the thread you will find similar stories that should help you come to the realization that kissing a Leo is not the best idea.
