I personally believe your reaction is very normal.
I feel like a very lucky man because men are after Laura all the time, she has chosen to be with me.
I play kissy on her all the time, whether she has been playing with someone else or not.
Many think we are newly weds when the fact is we are not married and have raised six kids together yet the excitement and newness of our relationship never seems to end.
Everyday with her is special to me. I think the lifestyle has added something. It has opened my eyes to just how special she really is to me. Makes me want her more all the time. All the attention she receives from others just enforces that.
I am never concerned about others being "better", they are just different. I know that she goes home with me no matter what happens at a club or party.
Keep hugging up and playing kissy face with her all the time, it makes life great!
