Please this woman is seeking for advice...

Without the build up of sexy pre-intimacy it can kinda take away from the sexual experience. Especially if theres none every single time.
U sure hes into you? Like sexually attracted to you n u sure he truly loves you?
If he did i dont think hed say things like that to you. Cos to have great sex i believe theres gotta be passion from both parties involved. It wont work if its only one sided. I dont think him being nigerian really has anything to do with it. All humans have sex the same. Its the sexual attraction between two individuals that makes the sex better n if theres love between them it can make it more intense i believe so anyway. So i dont think it has anything to do with his ethnicity or yours. I guess its possible that its different having sex with someone from a different ethnicity just in the way that theres slight differences in all races of ppl. Sometimes little things can affect ppl n they realize what they prefer. Or theyre just used to it. Maybe he prefers younger women or women who behave a certain way? Ask him for exact reasons n how u can fix it. Anyway goodluck
