I have been on hormones 17 days and have noticed prostate fluid leaking or just some type of discharge occurring more than normal while on HRT.  And by fluid leakage I mean a clear slippery fluid. Is this normal?

  That's seminal fluid without the semen.  I get that every once in awhile when sleeping since HRT, and sometimes before that.  This is caused by the multiple erections during the night while you are sleeping, normal prostate function.  Keep it clean down there, this is also normal seepage in normal males as well and will supply the jock itch fungus (tinea cruris) with the fructose sugar.  The fructose is added by the prostate during the normal ejaculation to charge up the sperm.
