Ok its a weird situation but here goes ok so I just turned 23 a few days ago. I've been married for a few years but me and my wife are seperated at the moment. I was with her for 5 years and only once was I unable to get an erection but that was due to some drugs I had taken. Well now I met this other girl she's very attractive and everything but the first time we had sex it was hard to get and maintain an erection I did end up getting an erection but I could feel it starting to go down so I had to kinda rush myself before it went soft. Its gotten worse since the first time now once I get to the point where we're getting ready to have sex its like a million thoughts are running thru my head and by this point any semi erection or whatever is long gone so no sex for me. But me and my wife still have sex from time to time and the messed up part about this situation is I could leave this other girls house and no get an erection but then I come home and if my wife were here I could get a lasting erection and sex would last for a good while. Like I said I don't know what the problem is but i'm convinced it has to be my mind messing with me. Anyone know how I can over come this barrier at all any ideas will be awesome. Thanks
