Is this groinal response?

So today I was playing around with friends and one tried to perfect my moves on parkour, and when he was touching me I started feeling a really strong tingling and getting semi-hard, in my mind I was panicking, this wasn't pleasurable in my mind I was grossed out and I don't want to get these. When I tried putting my mind blank for no anxiety it got better, but now I'm worried.

For the past 4 days I haven't come out of house because of it, I get this tingling almost like, I'm tensing up but I stay the same, all my comparing test I never get hard, I can only get hard to women but now I'm paranoid!

Please Help was that thing really arousal with my friend?

I think its just a groinal response. I wouldnt worry about it.

Yeah this sounds like the classic groinal response.

classic groinal no question.
