I am 18 years old and I have some problem that accures after having sex. It's from almost 2 years. After having sex I feel weak, tired with some joint pains, if I don't sleep or eat something sweet I feel like my knees are not going to support my weight. Some times there are pains in the testicles and chest pains /near the heart/ + my heart is racing very fast for a long, long time. It gets worse if I have sex more than twice a week. /I can say that I've had a quite late puberty, may be it's related?/ Thanks for your attention, I hope somebody can help me.
P.S.: the only tests i have done are blood tests and hearing of the heart, I sport a lot so the doctor said that my heart is fine but there may be some tachycardias /the doctors here are not quite good.../. Thanks again.
