Is this SA?

When i was in 7th grade me and my friend M were hanging out in recess when he asked me to blow him, i was weirded out by this but i didn't think too much of it since he might've been joking idk. Later that day we were skipping class together, we had this very secluded spot at the top of a stairwell, we were just talking like normal when he asked if i could jerk him off, i obviously said no but he kept pushing and calling me names like "pussy" and saying stuff like "c'mon why not?" i kept refusing but M kept pushing eventually i "agreed", i was extremely uncomfortable the whole time, after 30 seconds or so he slid his hand in my pocket and started touching me, this made me even more uncomfortable and i immediately pulled away and stood up, he once again called me a coward and what not but i left anyways. Im still not sure if this counts as SA (hence the question mark) but i still wanted to share my story, i asked a friend a couple weeks ago and i asked abt it on spacehey if this was SA and they said yes, but im still not sure.
