I can't stand kisses from my husband😬

I'm 8 months prego and since I got prego I can't stand his hugs and kisses. I love him with all my heart but for sum reason kissing and snuggling drives me crazy!! Like I feel like puking when I think about it. I love our sex...it's amazing but just no kisses!! Poor guy. I hurt his feeling because I don't show him that love...do u girls think it's just the pregnancy?? Or am I just being a bitch..??
