my DH used to ALWAYS say those things! He never made it known to any of our friends that we were trying or planning on a family some day. ALWAYS would shake his head saying no no no you're crazy! he'd walk away and i'd tell everyone "i'll just have to trick him into it some day i guess!!"
now i am pregnant and he now starts with "no more than 1!!!!"
i think maybe it's just not a guy's thing to talk about or mention TTC, know what i mean? not a manly type of conversation! infact i can't really picture my DH replying to people saying "We are trying!! bought some OPKs this month!"
