Will this ruin the friendship?

[Haha456]

If I tell my guy friend that I admire how strong his arms are?

[maximumpower]

Not necessarily ruin the friendship but its an indicator that you like him a bit more than normal.
Would be somewhat akin to his telling you that you have nice skin.
Either one isn't necessarily bad, but it's more "intimate" than normal friends would discuss.

[sonic_fever]

Wouldn’t ruin it but if that guy takes it the wrong way and he thinks you’re now falling for him he may distance himself going forward

[laurieluvsit]

No, guys love that!

More likely he will want to have sex with you immediately... lol

[FilmGuy93]

I don't see why that would ruin the friendship. It would come across flirty though. Just don't follow up on the flirtienss and you should be fine.

[Guy13]

No… I might blush. You may touch and let me know where it needs work 💪

[JPresidente]

Depends. Do you like him as more than a friend?

[darline19]

no. he would be happy to hear that. 😂

[katiesmuff]

No that should be just fine

[ThinkingofThink]

That's a compliment, make sure you tell that

[joeldalton]

Nope. He will appreciate the compliment.

[20yearsolder]

It shouldn't

[goodgirlsteven]

nope!

[In_Trance]

Eventually yes
