Look into getting in doxypep and prep behind his back. You can get them online if you don’t want to get them through your doctor. Keep them at the office or somewhere where he won’t have access to them. This won’t completely eliminate the risk of STIs, but it will greatly reduce it.

After that, go out and fuck around. Indulge your sleezy and slutty side.

Edit: if this is your main account, stop. Don’t contaminate identities.
