I have been suffering body aches and feverish conditions after orgasm from sex.infact i fall ill next day after sex even though i avoid lots of physical movement.As long as i have an orgasm,i suffer horrible body ache,tiredness and feverish conditions by next day and i dont get better untill i have treated for malaria.Could you tell me what could be the cause and if there is a medical treatment for this,since it has affected my sex life negatively,infact i get scared of having sex because of this condition.
