I think your symptoms are a combination of both mental and physical.
as we get older, erections can become more difficult, specially if we haven't taken good care of our bodies and have not eaten healthy and exercised regularly.
bad anxiety symptoms don't help either.
you have to be very relaxed to be able to have an erection for the nerves that cause an erection to fire properly.
the cialis not working is not because you are reaching a tolerance, it is because your anxiety symptoms and your age and nerves are at a level that the cialis is not enough to help
cialis helps reduce the action potential of the nerves which lead to erections. but if you have bad anxiety symptoms and poor functioning nerves, then cialis may not be enough.
let me know if you have other questions.
