Sara, thank you for taking the time yo care for your husband’s genital health concern. Unfortunately, the photo is totally indistinct, so other than saying it could be ‘this, that or the other’ it would not be of much help to you. So, if you can get a clearer photo …
I take it you are in the States, I am in the UK so I do not understand the realities of what not having health insurance actually means in practical terms.
For example you say you can get a pap smear, is this something you need to pay for, or, are somethings like the smear you can get for free?
What I am thinking is I wonder if there are Sexual Health Center’s or facilities that anyone can access for free?
