Theresa telling Syd that 'other things were effected.'

Did anyone else think that was a little too wrong for Theresa to tell her sister-in-law that Marcus was having some problems with impotence?

I know she didn't flat out say it like that, but it seems very awkward for a man's wife to tell her sister-in-law something so personal. That would be like my brother-in-law telling me about how my sister is having problems in bed or something. Just too awkward.
