mailing panties to long distance bf??

my boyfriend is in the army and just left a couple weeks ago to do training for a few months. we have been together for 10 months but this is the first time since we have been together that he’ll be away for a while for his job. yesterday he asked me if i would send him a pair of my panties lol. so i’m totally down but i’m just nervous about it. what if they stink or something by the time he gets them 😭 any other day i smell fine down there and don’t really have any reason to worry about it. my man has had every part of my body in his mouth so i’m assuming he wants them because he likes my smell?? idk i’ve never gotten the whole used panties thing but my freaky boy said he wants them stinky.💀 so do i just wear a pair and ship them??? i was trying to find advice from the baddies that sell their used undies online but they were talking about vacuuming seeling and all that??? i was just trying to throw a pair in a ziploc baggy, put that in a manila envelope and ship it??? idk also what about discharge stains???😭😂😂 it’s not a lot but it’s a think my vagina does and he doesn’t need to see all that 😭

thank you 🫶🏻
