A few years back dated a guy for over a year. I, being younger at the time, never had sex with him and never intended to, although we would often end up making out, but always with full clothes on. One time an incident occurred (I am not a minor, but still not on birth control) where I went home that night and worried as to whether or not I was pregnant. Well, obviously by now I know I wasn't. To this day however, even when I am fully clothed, if I lay on or near a guy, I have a paranoid thought inside my head worrying about pregnancy. I know it's crazy, but I'm not sure how to fix it. Recently I was worried at the thought that somehow I could get pregnant through his two layers of clothing, and my two layers (including jeans), even though I have no clue as to if the guy at this incident even ejaculated, (which most likely he didn't, there was no wet-spot as many bring up in other posts) How can I fix this, besides just getting birth control?
