5 year old advice

A couple weeks ago my 5 year old daughter was caught asking a little boy to kiss her.  I immediately asked her to come inside and I calmly sat her on the couch and asked her what she was doing outside and what she was playing.  She never told me that she had asked the boy to kiss her.   I proceeded to ask her "did you ask him to kiss you " and she said not at first and she said "I didn't want to tell you because then you'll be mad".  Right then she obviously new that kissing was not appropraite(even though thtis was the first time that she did it and we have never talked with her about this before).  My second concern is that she didn't feel like she could come to me and her father and tell is the truth on what happened.  We brifely told her that was inappropriate and that we don't do that...very simple talk because we didn't want to make a huge deal out of it.  We then had another talked after we got home that night and told her thatit's always important to tell the truth and that by telling the truth you don't get in as much trouble, if any but by lying it can make things worse.  I also explained that kisses are special and we only do it when we get married or to mommy and daddy and brother and sister.  We tried to make it as clear as can be.  
2 weeks later we go to my husbands softball game.  That same boy is there.   I trustfullylet her go run around and play but before I knelt down to her level and without even saying anything she said "i know mom, be a good example and don't kiss boys" and I sisd good girl your right and let her go one her way to play.  Leter more of my friends boys arrive and they are all playing together.  Later I I have my friend come tell me that Lexi is chasing all the boys asking them to kiss her and play boyfriend and girlfriend.  WE JUST HAD THE TALK 30 MINUTES BEFORE.  I don't know what to do, she knows that we don't like her doing that and that it is a bad choice.  I then confronted her on it and she denied it at first until i kept asking her.  So there are alot of problems here and I need some major help on how to deal with this.  Pleaese help

Hi, I have boys (5 and 4) and they don't really want to play boyfriend or girlfriend or anything----  but they have played house with kids where someone is the dad and someone is the mom and the rest are the kids.  Most kids play this----  pretty universal.  

And the boy girl chasing thing is pretty normal too in my opinion.  It's kind of like early flirting (my friends and I have joked).  And there are two twin girls on our street that now ride the bus with my 5 year old (they're 5 too) and one of them tried to kiss my boy on the bus.  I really do think that it is child play in my opinion and she is trying to get a rise out of the boys and play with them.  That's my honest opinion.  I just wouldn't go crazy over this.  She's not doing anything overtly sexual.

If I am missing something here----  let me know.  You may want to pay special attention to her tv time.  Make sure she isn't watching the Disney channel if you don't want her to see this type of thing (hannah montanna).  And does she have an older cousin or babysitter with a boyfriend?  Has she seen an affectionate duo?    

The not listening to you part is probably the biggest problem.  Impulse control is hard on 5 year old when they think something is fun.  Just keep at it.  

Most likely the boys will want nothing to do with her kissing and she'll get the hint.   Then she'll start to say boys are "yucky" and that will be the new phase.
