Hi m4444444,
Thanks for your question. Everyone responds differently to physical stimulation, and masturbation is no exception. Whilst some people may find that stopping masturbation just before climaxing (or cumming) makes sex shorter, it can just as easily make sex last longer for other people. It’s important to remember that there is no right or wrong, and to do what feels pleasurable for you.
If you want more specific info call 1800 451 624 between 9am-5.30pm Monday to Friday to talk with a sexual health nurse (like me). It’s confidential & free if you call from a landline. I’m also here if you need anything else.
Play safe,
Nurse Nettie
