Hi, I am a man aged 44 as I am writing. My problem is erection deficiency. I started to this problem a few months ago and it did not bother me but looks it's getting worse. When I look at my testicle sack, normally should hang loose between my legs when hot and shrinks into a tennis ball size. This process never happen again for sometime. I grew up without this problem and I feel my sex appetite is in jopady and it is. Healthwise, I am very fit and rarely get sick even if I had, recovery is natural. What can be the problem and how can I get through this situation. Pita Domingos, Mozambique.
