That's not entirely true. Excessive masturbation can result in the body NEEDING that kind of stimulation to reach orgasm. This can result in difficulty climaxing when another person is responsible for your pleasure.
This isn't a problem with masturbation itself as a whole, but with gripping your penis very hard with a "death grip". Using lighter touches and lubrcation occasionally will prevent this problem.
tldr don't go "fuck if i masturbate i won't be able to have orgasms"
