My husband secretly bought viagra too - but not for me. For his lover.

That's alot of effort to go to just because he's embarrassed. I'd be more concerned about his failure to be able to communicate with you if that is the reason he's hiding it from you. Also it's pretty sneaky in general I'd be keeping my eyes wide open from now on.

Im younger than my partner and he has tried viagra to a get it and keep it but also to try last longer. Men feel demasculated if they cant preform and feel we are not enjoying ourselves. Talk to him and trust him. You married him, you should know deep down if something else was going on. I would just say he is self conscious about keeping up.

I wouldnt jump to any conclusions about cheating or anything. He is your husband - trust what he says unless there is a specific reason to think otherwise.

I would think he wants to do something to improve his performance, and yeah - it would be something nice to do as a surprise.

If there are no other signs of cheating, I’d say he is embarrassed. You’re younger. You have frequent sex. Maybe he has noticed changes and is afraid of letting you down. You do need to talk to him about it.

Honestly could go either way.
He could very well be embarassed, or want to last longer. Try talk to him about it xx
