Last saturday i was with my boyfriend (im 15 and bisexual, male) and we both gave eachother oral sex and mutual masturbation. He did not ejaculate in my mouth but after we'd stopped i knocked my teeth on his braces while kissing which caused my gums to bleed. 3 days after and i have come down with a cold which could obviously be something else as other factors such as bacteria, cold weather or being upset and run down due to him breaking up with me. I'm just very worried as i hope it's just a cold and i don't want to have to be tested.
