Birth Control Pills

I would really like your help with this one. My boyfriend and i are not sexually active because we share a long distance relationship, so i don't see him very often. Im not on birth control so everytime we're together we have to use a condom because we are not ready for a child at the moment, not until after we're married. The problem is i've never had a orgasm and thats because as soon as my boyfriend starts to ejaculate he withdraw and i never get a chance to go to that extent. I just don't like the fact of taking birth control because i've seen some of the side effects it has on my friends and it turn my mind from taking them. My boyfriend and i talked about it and he says that the only way for me to have a orgasm is if he didn't have to stop so much to ejaculate, so i have to take into consideration the fact of having to take birth control. I just want to know if there is a birth control pill that i can take only when my boyfriend and i are going to make love and not take the ones for everyday, because i want to be able to enjoy our connection to the fullest. Please let me know if there's such a pill and can i get it over the counter instead of getting a prescription.
