I face with ed when trying to have sex with women other than my girlfriend. but this is only premature ejaculation when having sex with my gf.

ED vs PE: Ed & pe are both curable and easily diagnosed at home. Ed (impotence) is the inability to attain & maintain an erection satisfactory for sexual activity. Pe is exactly as stated - the man reaches climax/ejaculates sooner than desired, usually in just a few minutes. Cure for ed requires introspection as well as physical evaluation by family doc. Cure for pe is more mental plus lots of practice.
