Is it normal?

Every time me and my boyfriend have sex, something weird happens and honestly it’s embarrassing idk what it is but like i thought maybe it’s the fiction from like us going back and forth but there like this squeaky popping noise that comes from my vagina idk what it is but it’s not normal I need help. Me and my boyfriend are becoming more open to each other day by day and every time that happens it kind of kills my vibe and I get embarrassed I know I didn’t really explain it well I’m sorry.
