Pre-seed question

Britney • 24 madly in love with my amazing husband August 27th 2015 we tied the knot! Pregnant with our first!
Everyone swears by pre-seed but my husband and I never used lube to begin with we just never needed it. Would using this help or hinder our TTC?
I'm 24 and my husband is 31.
We are only one cycle in to TTC and BD 3-5 times a week. 
Just wondering if the TTC process begins to take longer than expected based on how both our families histories should we try it or not?
