Hello, I am fully aware that this is going to come off as a stupid question, but i need my mind to be at ease about all of this. My stepdad took a shower last night when he came home from work, and hung his towel back up on the shower thing. The next morning, today, I took a shower and had my towel next to his hanging up on the shower door. After washing my face, the final step when I’m showering, with my eyes closed, i reached for what i thought to be my towel and dried myself off completely, drying my face last and opening my eyes to see that it was my step dads towel. I was mortified and frustrated at myself for using his towel rather than mine. That means, the same towel that was on my stepdads genitals the night before, was used on my genitals as well. What’s the risk here? I’m feeling so anxious and sick about this, google has not been my friend on this issue as I’m reading that it is indeed possible. After inspecting the towel, it didn’t smell weird or have any spots on it or anything, and i don’t think my stepdad would disperse semen onto a towel and leave it for another use or to be used by me or my sibilings... so I’m just confused and scared.
