Need opinions

Sorry this is long i just needed to explain the whole situation. There is this guy that I like. He is really really sweet. We have known eachother for a very long time. Let's just say since elementary school. We was never in the same group of friends but we both got along with everyone. Lately we have been hanging out a lot. He is probably the most honest and sweetest person I know. Although neither of us is ready for a relationship right now we have talked about it. He is currently going through a divorce and has 3 kids (that doesn't bother me) he's been separated for a little over a year. I just had my divorce finalized last week. Which I've been separated since May 2015. In the discussions of relationships we've had he said that he won't settle for someone who doesn't give head or anal sex. I've never done either. Giving head is more like I will throw up all over you kinda thing and anal I've just never really done it. My ex bf wanted to and I agreed but I wanted to be in a serious relationship someone who I planned on being with possibly the rest of my life. I don't want to just do it with anyone. He said he's not compromising. I asked him for example... what would happen if for some reason it was physically impossible for me to do one or the other. Like say a medical reason or whatever it may be. Or like I'll say giving head what if I constantly try for him but throw up on him every time. He said he won't comprises that he knows what he wants. I guess with what my ex bf did to me it makes me feel like I gave my all in the relationship and I still wasn't good enough for him. I could have gone to the moon and back and it still wasn't enough. What if I'm compromising a lot for him and even though I'm giving %150 don't you think that he should be more understanding if one or the other doesn't work out? I know myself and I feel like the anal wouldn't be the problem it would be giving head. I'm 34 years old and I gag on my tooth brush everyday I've had how many years to grow out of it and I haven't. I don't want to take a chance and things not work out and I'm afraid that I'll let a good thing slip by if I don't. Yes he is a good thing dispite the not compromising. He actually left me a note on my vehicle today while I was working to tell me to have a good day at work and that he misses me. Any advice? I'm open to any opinions good or bad.
