Your symptoms sound temporary and related to long abstinence, increased sensitivity, and mild performance anxiety. Painful ejaculation after nightfall can occur due to temporary congestion or mild prostate irritation and usually settles on its own.
Ejaculating in 3–4 minutes is still within the normal range, especially after a long gap or with high excitement. Since your erection and second-round response were normal, there’s no major concern.
Next Steps
If pain or burning persists, or if you notice fever or blood in semen, see a urologist to rule out infection. Otherwise, this should improve naturally with time and regular activity.
Health Tips
Stay relaxed, avoid over-focusing on performance, and keep good hydration.
