This looks nothing whatsoever like herpes to me nor does your description sound anything like herpes to me. The pictures don’t look like herpes either. Nothing in your mouth or on your penis or around you anus (is that your anus?) looks anything like herpes to me. Itching in your eyes has nothing to do with herpes nor does back pain. And it sounds like you basically used condoms throughout the sexual encounter with the exception of the oral sex, is that right? Have you ever in your life had a cold sore on your lip? If yes, then you are extremely unlikely to get genital herpes from receiving oral sex either.
I believe that you are scared because this is your first sexual encounter after a long relationship with just one person and it is normal to be concerned in that situation. But don’t get too carried away here. I think you did things correctly with this encounter.
You are watching things very carefully and if you start to see water blisters in the genital area or something like that, then you can get worried. And they won’t be under the surface of the skin or difficult to see, they will be pretty clear. And if that happens, then you need to see a health care provider right away and have them swab tested. But I don’t believe that you need to be seen at this point for the symptoms that you have described to me.
Does that help?
