19 M dating 29 M from Mexico Where to Take Next Steps?

Hi as the title implies I am dating a 29 year old guy from Mexico. He lives in America now, but he just moved here at the start of the year. We have been on four dates and on the last date I asked where he saw this going and he said we are getting to know each other and seeing where it goes. I think him telling me this was a signal to me to slow it down. He also said he is not seeing anyone else because he works 60 hours a week so he does not have time. He said other guys on dating apps usually ghost him because they think he is ghosting him when he is just busy at work. He also mentioned the 10 year age gap. I don’t find an issue with it because him and I are not at entirely different stages in life. We are both trying to figure out ourselves as adults right now, just in different ways. I don’t think I need to find a justification though. He also said he does not have a problem with it, but he mentioned it so I feel like it does concern him. . Him and I hooked up on the third date and spent the night together in a hotel. I think this was a really impulsive decision on my end because I am now attached to him and will be hurt if he ends things. Should I put off doing anything sexual with him again until/if we are exclusive? Also, he is currently on a trip for the next week. Would it be best to wait for him to reach out to me? I feel like I reach out a lot to make plans after dates, but during dates he always comes up with ideas of things we could do together. When he left for his trip he said see you soon, so I took that as a good sign. I want to make sure I am not rushing things and am not entering a relationship based on impulse.
