Sex During Pregnancy

Hi ladies! I’m 18 weeks pregnant and the last couple times my hubby and I have had sex it feels so weird and different. Not necessarily in a bad way - not painful- and I’m still able to get off, but it feels like something is swollen or in the way in my vagina. Like there’s something sticking out further than normal that his penis kinda needs to get around. Like I said it’s uncomfortable but not painful and in certain positions I don’t feel it, but at certain angles it feels SO STRANGE. He said he can feel a difference too.

Has this been anyone else’s experience? Obviously the idea of things being bigger/swollen in my vagina makes sense during pregnancy, but from my google searches I’m mostly just seeing that it’s common for your labia to be swollen, not specifically anything within the vagina.

Thanks girls!!
