I need help

The other night when my wife and I had sex I failed. I was able to bring her to several very strong orgasms with her toys and was very hard while watching her cum. When it was time for me to fuck her I unable to keep my hard on for more than 10 minutes and could not cum until I jacked off on her while she fucked herself and came on her toys. I really need to find a local black man to become friends and get her interested in having him fuck her. I know she will love it once she does it. She knows I want her to fuck black men but isn’t sure it would be the right thing to do. I want her to really enjoy sex with someone bigger and better so that she knows what fun a good fuck is. I can’t wait to watch her with her first black man. Please contact me samcc4ili@yahoo.com
