Thanks for the query to H.C.M. Forum.
In my opinion your history is very ambiguous so it is very difficult to evaluate any diagnosis .
In my opinion you are not a patient of KLINEFELTER syndrome
As Klinefelter Syndrome is characterized by small testes, infertility
, eunuchiod proportions & poor sex desire.
In severe cases prepubertally with small testes or with impaired androgenization & gynecomastia.
As you mentioned that there is enlarged abdomen ( stomach ) .
Please get in blood for F SH , LH , estrogen
, androgen levels for evaluation of diagnosis.
Excessive hairs growth may be due to over production of androgen hormone .
If possible upload all reports with picture ( whole body).
Consult an Endocrinologist
and get his opinion.
Good luck. Dr. HET
