As long as the head of your penis was covered, you don't need to worry about gonorrhea, chlamydia, HIV, NGU, hep B, mycoplasma or trich.
You could get syphilis, herpes type 2 or HPV.
Shaving just prior to sex means that your skin could be irritated or have small tears in it, making you more susceptible to these.
You can test for syphilis at 6 weeks, though syphilis is uncommon in most developed countries, like the US, UK, Canada, places in Europe, etc. If you do have syphilis, you'll get a round, painless sore at the point of infection. You can get the sore between 10 and 90 days, though the average is 3 weeks.
You can test for herpes at 12 weeks, though most are positive by 6 weeks. Make sure it's a type specific IgG blood test. Please note that there are false positives on this test, and sorting that out can take a lot of time, and if you don't get symptoms within 2-12 days, you might not want to test.
There is no test for HPV for men. There is a vaccine for it, though it doesn't stop an infection after.
I wouldn't overly worry about this. You did use a condom, which offers a lot of protection. Even if she doesn't usually use protection, she did with you, and that's what is important.
