HIV / STD ?!? HELP

Okay so, 3 weeks ago I had unprotected sex (well not technically) I was In the moment, and he went raw but it never went in.. like at all. He tried multiple times but it never went in far. He had a bunch of sex partners and I didn’t know until after. I kind of feel nasty but now all of a sudden I’m sneezing and stopped up. ( a couple of coughs but not like that.) I think I’m being paranoid, but it’s just that my friend started telling me about his sex life and now I’m freaking out. I don’t think I should think I have HIV because it never truly went in. WE END UP STOPPING BECAUSE IT STARTED HURTING. I’m not sore down there, I don’t have any scares, my throat isn’t hurting and I don’t have a fever. I’m just stopped up and sneezing . I don’t know if it’s the pollen in the air since it is spring time or am I feeling guilty. Y’all talk to me.
