Do I have symptoms of STD after a sexual encounter?

I am straight but gay curious. Last week Saturday 5th August I had my first gay sexual encounter with a partner. He told me that he is negative. We both sucked each others nipples and masturbated each other. Some kissing was also involved. There was no anal sex. However, both of us put our mouth kissing each others underwear wrapping our genitals.

My nipple was a bit sore after he sucked them and whether a possibility he has any blood in his saliva when sucking them?

Also, when kissing each other's underwear, could some precum have been on our mouths?

My partner could also have accidentally touched his nipples with his contaminated hands. Then I sucked his nipples.

Also, his hands had some of his semen which he did not wipe dry and he tickled my nipples. Could his sperm have entered my sore nipples and cause STD or HIV?

It's because I felt a bit of a sore throat, feverish feeling with chills and a bit tired than usual just 2 to 4 days after this encounter, I am worried it might be the early signs and symptoms of HIV or STDs?

Thanks Joejoesmith. What about the sore throat, feverish feeling, chills and a bit tired than usual feeling 2 to 5 days after the encounter?
