AITA for not wanting to be intimate with my husband

Hi yall I (28F) have been married to my husband (33M) for 7 years. At first I didn't mind being intimate with him, but once we had kids my sex drive just disappeared! Our daughter is almost 4 and oir son is 1, when our daughter was born it took maybe 1 year or so to want to do anything. With my son its taking me a lot longer, I dont know if I just don't care about sex anymore or what. He is constantly asking to be intimate either once the kids are asleep or by letting our son play in his playpen and we get intimate. His love language is physical touch and mine is acts of service. I don't want to be constantly touched by my husband after being climbed on by our kids all day. He does try and help me with the kids but other times he gives me shit about needing a break because I'm overwhelmed I also have ADD and possibly autism(getting tested soon). I dont need sex like I feel he does. I have no idea what to do. So AITA for not wanting to be intimate?
