Meyer Stein asks:
Rashi says that Ba'al Keri is because of kalus Rosh so is different from other Types of Impurity. My question is that most times isn't one a Ba'al Keri for performing a Mitzva, either Leil tevilah or ones chiyuv Oneh. And it seems we are stricter with regard to one who has marital relations more than loynso.

The Kollel replies:
Even though the Ba'al Keri may have performed a Mitzvah of Leil Tevilah or Chiyuv Onah, nevertheless for most people it is difficult to perform the Mitzvah totally l'Shem Shamayim, without an element of Kalus Rosh also.
