The act of swallowing his sperm

Semen is known to contain hormones and proteins from the male, which could be useful to the mother to strengthen her immune system and improve tolerance. Scientists from Leiden University Medical Centre in the Netherlands tested their theory comparing the pregnancy history and oral sex habits of women. Oral exposure to seminal fluid seems to influence pregnancy outcome in a positive way. The study found that 73 percent of women in the non-miscarriage group regularly gave oral sex and 57 percent of those in the miscarriage group engaged in the sex act frequently. According to the Harvard School of Public Health, men who spent more than an hour and a half each week engaging in physical activity outdoors had a 42 percent higher sperm concentration than those who spent no time outdoors. A miscarriage is the natural death of an embryo before it can survive independently and is most common up to 20 weeks of a woman conceiving.

Q: Is it weird that a straight guy likes his own cum? I prefer to share it with a girl lick it off her, etc. A: I searched the archives and am happy to say that, in five years of this column's existence, I have not answered nor even received this question!

A fascinating study published by Dutch psychologists shows that, when women are sexually aroused, their tolerance to disgust increases — not just regarding oral sex or other sexual acts specifically, but across the board. In the study, the group of sexually aroused women felt less disgusted when asked to touch a "bloody" bone actually, it was red ink or put their hands in a bowl of allegedly used condoms which were actually not used, but covered in lubricant. The study also included two other groups of women who were not sexually aroused first, who exhibited normal disgust and avoidance responses. In my clinical practice, I'm always looking for ways to help women reduce their aversions to certain sexual acts or bodily fluids.
