I am a 53-year-old man. I am a widower with hardly any opportunity for female company. So, I have been using escort services and having sex with the women using condoms. Recently, I have become friendly with a like-minded woman and the relationship is moving steadily. Hopefully, it will result in a long-term thing including sex. I have currently not pushed for sex as I am not sure of myself due to my past encounters with the escort women. I will like to get myself tested to make sure that I do not in any way endanger my partner. I understand that even with condoms there remains a small residual risk. Hence, if you can kindly suggest some diagnostic tests, I will like to get myself tested and then only decide on further action.
