No, you are not being stupid. Anytime a spouse hides something...there is a problem. I would be concerned because you don't know where this is leading. It often goes from these types of sites to on-line chat to cyber sex with a stranger to physical sex with someone. Keep your eyes and ears open...this may be a pattern.
You're being stupid! And you are probably not giving him enough sex either
Not really a big deal maybe the 2 of u should watch together I have been married 12 years every once. And a while we will go out and its date night I will let her bring another guy back to hotel and she allows me to do the same I do enjoy watching her have sex. She has even escorted a few times I have no problem with it relaze u live 1 time
