If you are ovulating and a boy ejaculate in you, can you get pregnant easier?

Yes. Pregnancy occurs when sexual intercourse and ejaculation within vagina occurs during what is called your "fertile window": the 3-5 days prior to ovulation, the day of ovulation, and 1-2 days after ovulation. If you are trying to get pregnant, this is the optimal time for intercourse. If not trying to get pregnant, then some form of birth control along with safe, protected sex at all times.
