just started off last night with .5ml and within 2 minutes my face was as red as a beet. looked like id been scorched in the sun. secondly, my penis stayed hard almost all night! every time i would awake to roll over or just readjust myself i noticed it was hard!! i read where this is aside effect but my question is will the alnight erections go away. sure it comes in handy when my wife and i are gonna use it but unfortunately thats not always the case. an all night erections is a little uncomfortable. serious anwers will be appreciated.
