diminished sex power , you scared me man , I’m only 21 :) .What can I do to reverse this process , I’m 183cm. tall 75kg - normal weight.I’m student in Greece , I came 2 years ago and before I come I had hard rock erections,however,I was very healthy and was playing soccer in one team.It all started when I injured my knee and stopped any physical activity for 3-4 months.After that I could not run and for 8-9 months I started to feel problems with my heart.I started moving again , just to injure my other knee .. then I started going to the gym instead.I have and varicocele on the left testicle , this may be causing low T. levels , I’m not sure.So what can I do to reverse this process .. taking any pills?Or maybe start running every day .. don’t know , what do you thing guys.My erections sure are not as strong as 2 years ago.
