I have pain sometimes when I stay too long and don't ejaculate.
Rauppe, it sounds like you answered your own question!
Yes, extended foreplay without ejaculation will cause pain, it is affectionately called "blue balls." This is not really caused by the semen or sperm itself but by the congestion of the blood in your genitals. Surprisingly, women actually get this as well but it is more painful for men due to the fragile nature of our testicles.
You bring yourself to orgasm as many times as you want but it is always best to follow long foreplay (or many non-ejaculatory orgasms) with a full on ejaculation. Feels better too
