I think that this harness is for anyone; beginners or advanced lovers. Whether you are someone who has erectile dysfunction or not this is a great harness. The harness rests above the male's penis. If you are a male who has E.D. issues this is a great product. My boyfriend and I purchased this because he is rather young and has E.D. problems at 34 years old and he was getting frustrated at the problem that every time we tried to have sex he would go flaccid. This harness is a lifesaver! We had lots of fun with this. He got to enjoy having sex with me all the ways he wanted to without worrying that this one wouldn't stay hard. The dildo that is used with this harness feels very nice while its inside you. It's not the feel of those hard plastic ones that can sometimes hurt more than feel good. This one felt so good I couldn't have asked for a better feel. Just make sure to use some lube. This was our very first time with using a harness and it was perfect.
