I'm trying to ttc a boy but stumbling block

[3011busyyear]

I know it's not a guaranteed method but i notice one of the suggestions is for me to climax first. I very rarely climax during the deed with OH Don't get me wrong i do enjoy it but in the 11years we've been together i've only orgasmed a handful of times
How much of a stumbling block do you think it might be?!
