Okay girls, I need help!

Lately, after my boyfriend and I have sex, there’s a non-foul odor. Like it literally smells like sex. He’s noticed it the past couple of times we have been intimate; however, I’ve only noticed it once. It’s not a bad smell, not fishy or nasty smelling and he has even told me that it’s not a bad odor, just that he has noticed it. I don’t have any other symptoms..no weird discharge, no itching nor burning during sex or while peeing. I have had to use lubricant a couple of times and I use a clit sensitizer sometimes just to help get me in the mood. Those products are from pure romance and they’re not supposed to cause any issues. I am planning on scheduling a drs appt ASAP just in case. Just need some assurance right now is all. TIA 💋
