Want to conceive..

I'm currently with my SO of 3 years and I remember he used to tell me he didn't want kids. However for the past two months or so he always plays with my stomach and kisses it and says hello little baby (playing of course). Just last night he was telling me I would be a great mom and he wants to have a baby. 
I cannot be more excited! 
​Any suggestions on how to get a boy? Or get prego faster?? (: ty!
​Btw I am 19, I have two jobs and he does as well.
