Translation of "Ejaculation" in Japanese

There's nothing that ruins life as much as premature ejaculation.

早漏ほど人生を無駄にするものはない。

However, it seems that just because it's a 'low risk day' doesn't mean that you won't get pregnant from intravaginal ejaculation.

ただし、安全日だからって、中出ししても妊娠しないというわけではないらしいです。
