Lubrication

Jen 🇬🇧

What is the purpose of using fertility lubricant? I plan to inseminate with my partners sperm so I’ll already be lubricated from sex. Our only problem is that my partner can’t “share his seed” so to speak because of the pressures of conceiving and I have to finish him off. This will be our first try this month using insemination so any tips and advice will be most welcome!
