Thank you for your reply.

No, No, the butt cheek kiss wasn't always naked. He kissed my butt naked before, but there're times when I was not naked he still kiss it.
Like when I lay on my stomach in bed. I have underwear on, and he still kiss my butt.
I dunno, he just put his lips on my butt and give it a kiss. I just find it awkward. Perhaps I need time to get used to this type of stuff.

I dunno, it like I'm not use to affection. Another example I feel kindda awkward is this.
My hubby he works 12-14 hours shift everyday, so perhaps he miss me.
Everytime he back from work, if I happened to be in the kitchen. He would lift me up onto the kitchen countertop and give me a long kiss. Again, I thought it was kindda awkward.
We have a huge height different between us. So usually he have to lift me up or bend down to kiss me.

You see, other women they would be thrill if their husband do this to them. But I don’t feel thrilled.
I don’t know what is wrong. I don’t know if this have anything to do with my mother abandonment me, so subconsciously it haunt me. I know it my problem.
I have No regrets choose to married him though. He is an awesome husband, it just I'm under alot of 'emotional stress" from my mother, and it not letting me enjoy my marriage fully on the "emotional" level.
