I had sex 🧐

So multiple things I want to talk about but the main thing is last night I slept with my friend, he’s been there since me and my husband separated (were getting a divorce) he’s been there for years for me but last night things kind of happened I gave him head and his penis was I mean not really big I would say 5-6in and not thick so I was sucking him and then we’ll we decided to have sex things was weird and I was nervous because he’s my friend like best friend, and well he couldn’t get his dick to go into my vagina 😨 like was I to wet ? I mean I’m confused on what happen .... 😂 like he couldn’t really get it to go in idk if he just wasn’t really trying or what was wrong but I’m trying to explain it so maybe y’all can tell me why and what happen yes it was a funny experience but Idk what to think lol also I’m starting to feel weird like I cheated on my husband but we’re in the process of getting a divorce maybe cause it’s my first time having sex with someone other then my husband in 7 years..... but like my friend he didn’t cum like he tried to say we needed to stop so I was like what’s wrong and he said I just don’t won’t to cum inside you and I’m over here like I don’t even think you put it in like he was struggling to get it to stay in like it was just embarrassing...... so advice please

OH AND on top of that he hasn’t replied to my messages this morning and he usually calls me on my way home when I leave his house he didn’t do that last night and he didn’t reply to my message this morning but he read it .... did I do something wrong ...
