My husband has been taking Cialis for 2 plus years behind my back, I was giving him a break because I did not want to put pressure on his already hectic life, he keeps his computer hidden from me, I am 46 and living in a sexless marriage for a long time,should I be concerned I feel uncherished in my relationship

Yes you should. I would be curious why he is taking the Cialis. It could be something as simple as him masturbating or he could have someone on the side. It is impossible to say, but you need to talk to him to ask him what and why.

Cialis is used to treat erectile dysfunction. If he has been using it for two years, it must be working, otherwise why would he use it at all. Or, if it wasn't working, he'd seek out his Doctor for other options.

Yes, I agree with Craven- you need some answers.
