my husband is constantly wanting affection. he wants me to constantly either make out or have sex. feels like he doesn't get it. I literally just had a baby. I'm emotionally exhausted I'm tired from caring of her all day then going to work. he only has her for about 5 hrs a day. I keep up with the chores and we have 2 big dogs that still need attention. it's not like I don't love him but when he says he doesn't feel the spark with me it scares me. I'm not a affectionate person he knows that. I love being romantic through deeds not through sexual things....I don't find that romantic but we married for life so idk what more he wants
