Didn’t use protection

Earlier this month I had a hook up with a “friend”. Who’s much older. I have a partner and we are in an open relationship. This is my first time sleeping with someone new in 12 years. So this hook up was someone new that I slept with. The sex was consensual. BUT I told him that I am not on birth control. I was under the impression he would use a condom. We were role playing and I was bound. He went ahead and penetrated me without anything . I told him I was very upset by this. He found it funny. I am upset because I don’t think it’s right he found it okay to not use protection. Now I’m scared I’m pregnant, or worse have an std. it’s been 2 weeks but my period isn’t due for another 9 days. Also, how long do I have to wait to do an STD test ? I am scared he gave me something... I feel “itchy “. Maybe I’m over thinking things and it’s a yeast infection from him going anal to vaginal. But I am very stressed out by this! I’m upset he doesn’t seem to think its anything to worry about. He won’t even tell me if he’s clean. He’s a lot older ( 50) and seems to think he can’t get anyone pregnant because of his age- how ignorant !!! Please don’t judge. I am just looking on advice as to when I should do a pregnancy test and std test. Also I am very embarrassed to see my family doctor. I feel very ashamed and upset .
