Lost !!!

I got 2 questions

1- I’m still virgin , I got a bf and we gonna get married soon but the issue is I don’t feel that I’m turned on easily , is it normal?! , I feel like I lost appetite for it , a while ago I felt so horny for several times before that I wasn’t and after this period I’m not , and that scares me I’m 29 years old

2- Im from Middle east I donnu the tradition of europe , But is it normal like when I say no I’m gonna pay and I insist once he says ok and let me pay is it normal ?!
