Tell me your story!!!

Alright guys, today i bought preseed, cause I've heard good things about it. But the thing is, I'm not gonna tell my husband that I'm gonna use it... so my question, if i use it, then he goes down on me, is he gonna notice? Like the taste or smell of the cream or anything? And give me any other tips on it...

Today is the first day of my fertile window and we plan on doing the dirty either every day or every other day of this time 😊 any pointers would be appreciated!!!
