hi, I have been with my partner since January and a few things have come to light. He is 29 and I'm 24. He has been completely honest with me and told me when he was in his early 20s and single he was into swinging but he says it was just with single women (not orgys ect) I feel really uneasy about it as I feel there is more to it. At the end of the day it is his past but is this a red flag or something I should not have to worry about?
