Extremely Hard Erections

[BananaStim]

Hello Everyone,

Just entered my 3rd week of estim play. Still learning but definitely progressing. Have a 2B with 4mm Loops and a moaner. While I have not reached the HFO as of yet, I have noticed that after a e-stim session if I finish the "manual" way my erection is super hard. Like really really hard. Not complaining I rather like it, it was just an unexpected very enjoyable side effect.
