There is no medically safe way. Teen aged men are regular sperm machines churning out testosterone, sperm and semen faster than most women can take it away.

Try some negotiation. Women can enjoy sex with or without orgasms of their own. As a young woman, I had many more sexual encounters (digital, oral, vaginal) without an orgasm than with one. It only takes a few minutes for a quick handjob or blowjob or real quickie (her choice) and you are more comfortable.
