Hello cecefromdablock, Welcome to the forum. The symptoms that you are experiencing are because of allergy that you have developed. As people get allergy from cold, allergy from some food or medicines, similarly you are allergetic to SPPA ( semen plasmo-protein allergy). There is a type of protein in the semen that you might be well aware of, causes diarrhea, tongue hurt, stickiness in the throat, inflammation or sensation of having thrush down the throat, etc. Anti-histamin (antiallergic medications) can be of a little help. Use antiseptic mouth wash. Change your brush. Floss your teeth to feel better. It can also be due to anxiety, stress or some emotional issues. If you do not have a high immunity level you can easily get infection from E. coli and other parasites, bacteria or fungus. Yes, such activities expose you to risk of getting STD. These infections are highly contageous. There are medications to help patients cope up with the diseases but it all depends upon their co-operation with the doctors and self-health care. These infections lower the white blood cell count which are the germ figters and make people really weak. You are in need to consult a doctor, openly come out with your history. You should get physically examined and get blood and urine tests done to rule out STD. You should also make sure if your partner is carrier of any disease. Take care.
