This might seem like a stupid question but...

Please don’t all bash saying Lol I’m 26 years old already have two kids been trying for number 3 for a while, anyway we’ve been married 6years so basically when we have sex I prefer to put his boxers on my like right in my crack 🙈🤣 if that makes sense coz I hate when cum all runs down me and goes over the bed. But this got me thinking would this soak up sperm 🤷🏻‍♀️ and stop us getting pregnant 🤔 sometimes he will leave his dick in for a few mins afterward before he takes it out, sometimes he pulls it out straight away. But anyway as soon as he pulls it out he passes me his boxers to put in between my legs. ( just had sleeping on wet cum stained bed sheets ) so we’ve been doing this a while. Anyway Will this affect conception?
