Try These Sex Positions If You Want a Kid Running Around the House ASAP

Snuggling up to your partner before getting it on has its benefits, especially for men. Joshua Hurwitz, M.D., an ob-gyn with Reproductive Medicine Associates of Connecticut, said in an interview that getting some skin-to-skin action before jumping each other's bones can increase sperm activity.

"Sperm counts in the ejaculate often will be increased if a man has more arousal rather than less," Hurwitz explained. "So, in quicker ejaculation, probably the sperm hasn't had enough time to concentrate in the ejaculate. If men warm up, so to speak, through foreplay, not only will it fuel arousal, it also probably load the ejaculate with increased levels of sperm."
