Mommas with kids of the same gender

Any mommas on here who have all boys or all girls? If so, do you ever feel like you’re missing out not having the other gender? I have two girls & it feels like everyone around me has both a boy and a girl, & sometimes I can’t help but feel a little jealous. Don’t get me wrong- I am so thankful & blessed to have my sweet girls. I just don’t know why I feel this way sometimes?! Does the feeling go away after awhile? Help! (Husband got the “snip” so having a 3rd isn’t possible for us). I hate feeling this way!
