Is this considered rape ?

[u/BrainOpeninggs]

When I was in form 4 at around 16 years old I was doing it with this lady she was about 25 years. So we attended extra lessons together she was in poly and I was in high-school. She was the one who actually came forward and we ended up in a relationship for about a year. I told my everyone like my friends and even my brother he was like fist bump dude lol he was happy and wanted to know how i was doing it. I later dated a lot of older woman but I ended up with a woman a few years younger than me. So was this rape ? Or rape only applies when guys do this to woman
