"I have been with my partner for almost 10 years. 2 Years ago I stupidly had a 2 min sexual experience with a girl and totally regret it! I stopped what I was doing and ran. I couldnt bear to admit the truth, I love her so much and could not bear to lose her! She is my sole mate. We are now engaged to marry but the guilt still hits me hard.. Reason: I have no idea....drink was envolved but not to blame."
