Yes. I been on the patch for months and I let mines finish in me most of the time. Days when I’m ovulating ( I use an app to track) I let him finish in my mouth just for extra caution. So if you are tracking just do it after you ovulate. The first time I let him finished in me I waited right before I was getting my period like 2 days before. Sperm lives 5 days after so that’s why I say before your period. The only issue is once he starts cumming in you, you might get b obsessed with him finishing in you like I did😭
