While doing sex my spirms get out without satisfying my partner so what to do?

More stimulation. Sperm comes out when men have an orgasm. This is satisfying for a male, but a woman needs a lot more than for a man to ejaculate into her vagina. Women usually need much arousal to achieve satisfaction or climax. It is your job to find out what stimulates or excites her. You probably need to play, stroke, rub or lick her clitoris. She might like you to kiss or suck nipples. Do this before insertion.
