Male Indian Flying Foxes Pteropus giganteus that spend more time performing oral sex on a female also spend more time copulating with her. In humans, men who spend more time copulating with their regular partner also perform more "semen-displacing" copulatory behaviors e. We investigated whether men who spend more time performing oral sex on their regular partner also spend more time copulating with her and perform more semen-displacing copulatory behaviors. We proposed and tested the ejaculate adjustment hypothesis for men's copulatory behaviors: Men adjust their copulatory behaviors to increase their sexual arousal and consequent ejaculate quality, thereby increasing their chances of success in sperm competition. Two hundred and thirty-three men in a committed, heterosexual relationship responded to questions about their copulatory behavior and sexual arousal during their most recent sexual encounter with their long-term partner. The results indicated that men who spend more time performing oral sex on their partner also spend more time copulating with her, perform more semen-displacing copulatory behaviors, and report greater sexual arousal.

I will say that the odds are slightly in your favour if you do manage to orgasm as the muscles involved help to propel sperm towards the egg so it progresses quicker. Saliva contains enzymes and other agents that can damage sperm and hinder their journey towards the egg.

Is it possible to get pregnant from oral sex?

It is very unlikely that a woman will get pregnant from oral sex. Pregnancy can only occur if semen comes into contact with an egg. Swallowing semen will, therefore, not result in pregnancy under normal circumstances. The digestive system does not connect to the reproductive system. Therefore, swallowed semen cannot enter the vagina, uterus, or any other reproductive organ that would allow sperm to fertilize an egg.
