Used to sex toys?

Idk if it’s because I’m used to my rose toy but I feel like I can only go while using it My man doesn’t suck in bed but I get it if he can’t make me go maybe he’s not doing it right idk he’s the biggest thick guy I had in my life but I also noticed after having my 2nd kid (she’s 4 now almost 5) down there is just dif feels not as tight but also when I cough I pee or run fast idk anyone dealing with the same issue Ps I do love my rose toy
