so two days ago my buddies and i went to a strip club, things got a little out of hand, and i ended up getting a protected blow job from a stripper, this was my second blow job ever(first one ever was about 3 months ago), during the process of the blow job i was trying hard not to ejaculate because i ejaculate fast, the blow job lasted about less than a minute, soon after like 5 minutes my balls started to feel a little heavy, i wouldn't say they hurt cause I'm not in pain, but more that they feel sensitive, kinda like if i had blue balls for a longer period of time. its been two days, and my balls feel the same. I feel like they feel like this because i resisted hard not to ejaculate, and Every time i pee, i pee perfectly fine, no pains or stinging at all. i started to have little anxieties about getting an STD because this is the second time so I'm not as experienced, what do you guys think the problem is ? or if this is a type of symptom of an STD?, a little worried.
