Can I get pregnant if he masturbated before sex?

My b/f came inside me but earlier in the day he mas*erb*ting ...and I was wondering since it takes about 36 hrs so that new sperm to form is there any way that I can get pregnant by him coming inside me???

YES !!! DEFINATELY !!! If you actually did this very recently I would advise getting the morning after pill immediately. You're 18 so any pharmacy counter has 'PLAN B' emergency contraceptive (EC) on demand - no prescription needed. EC is 85-75% effective at preventing pregnancy, and the sooner you take it the more effective it is.

yes!!! you can!! just like bimjob said go get that emergency pill be more careful

(cont.)
EC has a chance of working up to 72 hrs after the 'event' (some studies say up to 120 hrs). It is not an abortion pill. It works EXACTLY like regular BC pills, just with a stronger dose. In fact reg. BC pills can be used. ( http://ec.princeton.edu tells you how.)
Sperm will wait around for 3 days in your body waiting for an egg. EC stops the egg's release. It will not keep you 'safe' for the rest of your cycle, however.

Good Luck !!

Babydoll, strongly consider going on the BC pill, to prevent unwanted pregnancies. Or at least keep condoms around.

Also, everyone, consider keeping emergency contraception in your medicine cabinet. I'm not promoting rampant rutting, I'm simply saying that all pregnancies should be welcomed by excited parents, not dreaded by frightened, lonely mothers-to-be.

YES you STLL CAN JUST USE A CONDOM!!
