Also guilty. A huge mistake when the best male friend becomes a FWB.
When its girls, for some reason it has not ever really been a problem. Like someone else said, its chalked up to a fun and crazy night - drinking, dancing, kissing, making out..... and then nothing more. No expectations like you get from guys.
I've been lovers and deeply in love with my BFF since high school. We grew up as sisters and have a very tight bond. When she told her husband that there was a big part of her heart missing, he helped her find me, after I was torn away from her. The night she finally rang after getting my number, she came to see me. The first thing we did was run towards each other and cried as we stood there in each others arms. Both of our husbands know just how deeply we are in love with each other, and won't do anything to destroy our love and bond. So yes we still sleep with each other
