Is it normal that i am so terrified and nervous to kiss my boyfriend?

Hi everyone, thank you for taking the time to read this, it really means a lot! Well I've been in a long distance relationship with my boyfriend now for 6 months. I'm 18 and he's 21! I've never had a real relationship before so even saying the word boyfriend makes me just a bit uncomfortable! He is going to be coming out to see me real soon in a few weeks and I am so nervous. He's had A LOT of girlfriends, and he's told me the things he's done with them. He's a virgin, but he's done other things with them, which also puts me more on guard since I've done nothing at all. He tells me he wants to spend a whole day making out with me and that made me more nervous because I don't know how to kiss! Or make out! Hell with it! Both! And I'm the jittery nervous person who if he would lean in to kiss me I would like make a weird face out of nervousness and freak out doing who knows what and probably kiss him all wrong and just have him be so weirded out! And I kind of just wanted to tell him that I don't know how to make out but then I'm afraid that would weird him out or scare him off. So I don't know what I'm going to do about the kissing, it has me depressed and stressed because the last " relationship" I was in, I was nervous to kiss that guy and I was like freaking out and everything and kept giving him quick pecks on the lips and turning away and hiding my face and he dumped me the next day before valentines day. So I really don't want to ruin this relationship with this new guy that I like SOOOO much. :( But anyways, It also annoys me because at the beginning of the relationship he told me he was a virgin, and I was under the impression he had done absolutely nothing which was a surprise to me because he's really good looking and has had a lot of girlfriends. So I was shocked just a bit when he told me but I believed him. Then just a while ago I decided to ask him again just in case if he had done anything else with girls and that's when he told me he had done everything but actual sexual intercourse. I got upset at him because in my belief ( and I'm not judging anyone or him for doing it what he did), so I got upset that he told me that like 5 months into our relationship because I don't consider him a virgin. I wasn't mad at him or judging him for it I just wish he had told me at the beginning. And I don't really believe that he is a complete virgin even though he has told me over and over that he is and that he had his reasons for not actually having sex. I did believe him after he kept telling me, but I'm still "eh" about it. Oh and he's going to be coming out and be 3 hours away from me staying at a friend's house, and he wants me to stay the night there for a week with him, but that also sounds kind of weird. He's told me he doesn't expect anything from me. I also don't think staying in someone's house that I don't know would be rude and uncomfortable. And he's also asked for pictures of me in a bra and stuff which I did not send him.
