Are you using a spermicide? You mentioned wanting to use more than just a condom. I am allergic to spermicides.(noxonyl 9? or something like that, I cant remember how to spell it!!) After using those I was just insanely uncomfortable. It is pretty common for women to be allergic to that I guess. There are alot of different forms of birth control. You can go see a doc or go to Planned Parenthood where it is based on your income. I am so glad to here you are being responsible and smart!! You can also search the web under birth control, there is alot of info there.
