If you really do not want to get pregnant, then I would use this method only in conjunction with charting or condoms during the fertile window. When men get aroused, as with women, their bodies secrete a little fluid to ease penetration. In the case of the man, the fluid is semen and it does contain sperm, therefore, you could get pregnant this way.

It happened to me when DH and I had just met and were dating (but I lost the pg).
