Mikvaos 8:2-3

Mikvaos 8:2

The following men must immerse because of a seminal emission: let’s say that a man saw that his urine came out in drops or was murky. If this happened at the beginning, he is clean; if in the middle or at the end, he is unclean. If it happened from the beginning until the end, he is clean. If it was white and viscous, he is unclean. Rabbi Yosi says that the rules for white are the same as for murky.

Mikvaos 8:3

If a man discharges thick drops from his male organ, he is ritually unclean; this is the opinion of Rabbi Elazar Chisma. If a man had sexual thoughts at night and awoke to find his organ heated, he is unclean. If a woman expelled semen on the third day following relations, Rabbi Elazar ben Azariah says that she’s ritually clean. Rabbi Yishmael says that sometimes there are four periods between intimacy and expulsion (a day and a night each being a period), sometimes five, and sometimes six. Rabbi Akiva says that there are always five such periods.
