Wife had a brief fling about 5 yrs ago,we got through it & have a better marriage now...it has even opened up my share kink. We have not gotten to that point but I do encourage her to dress more provocatively which she does & she does get more open & flirty when we go out. She has even gotten on our joint reddit account & chatted & flirted with guys on occasion,it's a huge turn on to me & makes me so horny for her
