Hi,thanks for query.Please relax
there is nothing serious in it.At times due to anxiety,declining hormonal levels this can happen.It is possible that you might have retrograde ejaculation
means the duct which carries semen from testis to urethra
has some problem with it and you are ejaculation inside.Please consult a urologist
and take his help.along with this also checked you lipid profile, blood sugar etc.
wishing you good health.
