Do you think penis size is a factor?

Jessica • TTC baby #3

I had an idea recently that part of the reason why I havent gotten pregnant yet is due to the size of my man's penis. He is quite well endowed and I'm petite so i was thinking that he may be overshooting my cervix. He is going to try pulling out a little before he finishes to see if that helps. What do you ladies think about it?
