confused...please help.

About two years ago I met a paraplegic guy online, that I was insanely attracted to. We went on a few dates but got so nervous became awkward and silent. I still got the courage to tell him I really enjoyed myself and would like to meet him again. He told me he wasn't looking for a relationship and that I seemed too innocent for him. I told him that I am not great with relationships and wouldn't mind a physical thing. I was a virgin. We have had an arrangement for two years now. It took me awhile to get past my nerves and not be completely weird around him.

As our relationship is purely physical we barely have any deep conversations. we also don't meet often due to our schedules but I wanted some input on two things. it could be nothing but I am curious to get some unbaised opinion.

1. he has mentioned a few times thay he is happy to just focus on what I want in the bedroom. So I feel like the focus is mainly on me. But he also barely plays with me or kisses me. I can understand not kissing on the mouth (as that may be more for relationships) but he doesn't really kiss me anywhere else. Is this normal? Is he fucking me out of pity?

2. ‎the last time we met...he suddenly asked me if I was going to do this (I was going down on him) with my husband. When I told him I wasn't sure if marriage is for me he proceeded to ask me if I want children...seems like an odd time to bring this up. Not sure what to make of it, especially because before we met he had also texted me to ask if it were upto me, would I want to meet more often.

The last time was also the first time he got completely naked (usually he only slides is pants down to thigh level) and also the first time he tried the missionary position with me (he can't hold this position for too long).

My apologies for the long post but I am a little curious to know some thoughts around it.
