I get this also and most times, I do some stretches, work around the house/property and it goes away. I find if I sit around too much I start to ache, especially in the winter time. Part of it is that I'm older and I can't fuck like I did 15 yrs ago. heck, it's hard to do anything without something hurting. the side effects of tadalafil are minimal compared to Viagra for me. sometimes, I take 10 mg every other day about twice a week. it's more natural too, and lasts. no getting in the mood, taking a pill, and waiting for it too kick in. and that can cause anxiety. now, when the mood strikes, I'm hard. big cock ready to go like always. what was difficult was swinging a big cock most of my life and all of a sudden, it's not working too well. I had never had a problem before. so Cialis, gets me past all that.
