too much sex!!! 😍

My boyf and I have been ttc for almost 4 months, with no luck yet. we have been really going at it lately and haven't been able to take our hands of each other! We've been having sex sometimes 3 times a day and has left me pretty sore, I've been using ky lube but I have allergies to most lubricants does anyone know of any lubes that don't kill sperm and won't irritate me ??
