Ok im freaking out here. I had a girlfriend for over a year and we'd have plenty of sex, and i never had a problem getting it up. Now we've both moved on and ive been hangin out with this other girl. We were in bed the other night and things got hot and she was basically dry humping me and i had a boner, then once we got our clothes off, we were still making out but my dick got soft! She was jerking me off but still nothing! Im really freaked out and dont know what to do or what the problem could be. Some one please help me out.
It sounds more like a psychological thing to me - as if you feel guilty about cheating on the first girl you mentioned. This is a common reaction in such circumstances - in fact it's also quite common in husbands who have been widowed from their wives after many years. Although there is nothing legally or morally holding them back, they can still feel as if they are cheating on the memory of their late wife & simply can't get an erection. However, this does usually tend to sort itself out over time.
