So I'm starting Cialis 5mg a day as needed for erectile dysfunction due to side effects from Metoprolol. I've cut down my dose of Metoprolol to about 37.5mg a day. I have no lack of interest, just my penis goes soft without manual stimulation. If I stroke it, fine, but if I'm having sex, for the last year or so, since I started the meds, it will periodically go soft without constant stroking which is highly annoying.
I'm only 33 too.
