Hi guys, bit of an embarrasing question for a guy my age, im 25 and have been with my fiance for over 2 year. And i still find her as hot as the day i met her, which is very hot. Trouble is over the last 7-8 month i start to worry about losing my erection during sex and even when we dont have sex. My heart starts beating like mad and alot of the time i try and put sex off and say im tired etc. Only recently i talked to her about it as its starting to impact on our relationship and makes me feel like im half a bloke and makes me depressed. Im not exactly lacking in the size department so im definately not worried about the size. But no matter how hard i try i cant get the thought about losing my erection out of my head. Can anyone help??? Big thanks in advance for any advice.
