Itchy after sex?

[mrpanickguy]

Hi, I have a question.
6 Days ago I had protected sex (lets say one night stand) with a girl. I am not sexually active (last time was 3 years ago) and under no circumstances we removed the condom at all during the act.
Thing is after 1 day I feel moderately itchy in my pubic area and after I took many hot showers it still persists on. I looked a lot of times if I could find any pubic lice, even tried with a comb but I couldn't find anything unusual in the comb, also no spots or anything weird on the skin in my pubic area. 6 Days now i still itch and i can feel a light burning at the tip of my penis. It's not really serious itching just moderately, and as I mentioned no red spots or anything odd.
When I walk it feels itchy, but when I sleep not so much.

Do you know what it could be?

I am generally a panicky/paranoid person when it comes to health, do you think this could be due to stress or anything panic related?

I haven't been able to find any red bumps, eggs or lice however the itching got better and I don't itch so much as I used to. However the burning / stinging feeling on the tip of my penis got a bit worse, I don't see any red spots or anything weird and it doesn't hurt when I urinate. Could it be from stress or anything related?

Symptoms of a lice infestation include severe itching and red bumps on the skin. The black eggs and small whitish lice may also be visible.

Before going to bed, apply cetaphil face wash liberally on your pubic hair and blow dry. When you get up in the morning, rinse it out. NIts come out really easy. Cetaphil works better than lice shampoo.

Another thing I should mention.
I have a generally an irritable skin and was sleeping at the other persons house for the few days.
If it's pubic lice what should I look for and what should I do?
