Clear sticky liquid come out from penis if i think about sex, sneeze, cough, passing stool or lift weights. is is normal? is it due to prostatitis?

Prostate fluid: Yes, the prostate may be over full and you may need to relieve it of the pressure by ejaculating a few times. But, you may also just be in your prime and your hormones are working over time. This sounds like a normal phase of being a young man. But, if there is any risk that you have a sexually transmitted disease you should get tested.
