== Sexual intercourse == 

 Hello, Tstrobaugh . I do not see how this edit by you is helpful to the article. For one, penetration of non-sexual organs does not lead to pregnancy unless it is by anal sex where semen has leaked into the vagina. This, however, is still a rare occurrence to get pregnant by. People do not get pregnant directly through anal sex, and certainly not by oral sex. Thus, I feel that this addition to the lead is confusing and unneeded.
