I'm not exactly clear on what your question is - you mention both penile fracture & erectile dysfunction - these are 2 different things. I think we can rule out any form of ED since obviously you're still getting erections, having sex & masturbating. Also, I think you would know beyond any doubt if you had a penile fracture - first, it's extremely painful & would almost certainly result in a very deformed, bent penis when erect, which you would definitely notice, and I doubt you'd be able to engage in sex normally. I don't think you have anything to worry about - if anything traumatic actually happened, you would have noticed it by now.
