Sex changes!? Help.

Hey guys! I’m sorry if this is TMI.

But I am 36 weeks and 5 days pregnant... last Saturday (35 weeks and 6 days) my boyfriend (baby father) and I had sex and he recently told me it felt looser.. (I felt a bit insulted) because knowing he’s the only person I’ve been with and my hormones are EVERYWHERE, I be wanting him..... BAD! (Very horny) and I’m not sure if that turns him off now. I really don’t know how to feel. I got upset with him. Back in the earlier parts of this pregnancy my sex drive was really off and he wanted me...I mean I know that your vaginal discharge/cervical mucus increase and change but I’m not sure because it felt great! Is it because this is my second pregnancy and I’m due in a couple weeks? 😩Any advice? 🙍🏾‍♀️
