I can as much as I want....
I was debating with a girlfriend yesterday. ..she said she's only able to orgasm once from oral and seldom from sex and she needs breaks...I never knew women needed breaks lol...she also said she rarely masturbates from fear of desensitization...I do it daily. ..and I have no issues. ..she said she masturbated before sex once and was unable to orgasm. ..
I believe it's due to her partner and her mind...imo
