The mods won’t let me say the DUI backwards word so I’ll use DUI instead.

I’ll try and keep it short, my gf and I have been together 5 years. We don’t use protection as she has an DUI. we are very comfortable raw and I like to finish inside everytime. She has really bad stress about getting pregnant when I finish inside, so she either wants me to pull out sometimes, or when I finish she quickly tries scooping the semen out and makes me stop thrusting. My opinion is that the cum is already in her so we can just continue but she thinks it’s safer to remove as much as possible right away. She also wants to have less sex to “lower our chances of getting pregnant”. What are your thoughts? Is an DUI fully safe? Should we really limit our sex? Should I be worried about finishing inside everytime?
