We almost went down that road a couple of years into our marriage when my size was an issue for her and we were talking about cuckolding (i've been one all my life) and she was really concerned about discretion etc. and we discussed about her having sex with him again, as she knew him, and missed the sex with him, but it was her that decided it would be a bad idea, so we let it go. I have been able to watch a few old home movies of them having sex, and I totally understood why she struggled sexually with myself. So, yes, if it was only the sex, she would, but he was quite an asshole as well.. so would have gone pear shaped for sure.
