Hi doc, i want to ask a question. My boyfriend and i did an outercourse 3 weeks ago, we rubbed our genital together. He did not ejaculate, and i'm sure there was no penetration. There was no significant precum, probably just a drop or two. There's no significant physical changes on me, either, and my period should come this following week. Should I be worry about anything? I need a further education, cause I'm freaking out and scared to death. Please response. Thanks for your time.
