I bought my first sex toy

100% the most mild confession on here but I’m aware of how sexually repressed i am and i needed to vent this out. Im sat on the street rn i bought it like 10 minutes but I’m still so stressed about it.
Im a tourist in Japan and i was exploring a regular souvenir shop until i got to the top floor and ive realised over the last week that the back/top floor of shops in japan will have the 18+ section. I was just wandering through the shop until i had go though a curtain saying “you must be over 18 to access this area”. I got through and its full of vibrator, lube fleshlight, etc. It catches me by surprise but is see two other group just browsing through it all (one foreign couple and a group of 3 japanese lads). This makes me feel a little less awkward to just look through. And so out of curiosity i look through until i start thinking what if. What if i buy something? Men have all sorts of sex toys all the time so why dont i? No one will know. The thing that convinces me is how much cheaper they are compared to uk prices. I toss a coin, it says head and so i pick one up. Its a red box with a small lable on it. I ask a worker nearby where i pay and he says the 2nd floor. I now have to walk down 4 floors to the tills with a box, in my mind, very obviously a sex toy. What else would hide the packaging? At this point im shaking its the most vulnerable thing ive ever done and now i have walk past everyone to pay. I get to the till red faced and shaking. Theres 5 tills, 4 men and 1 woman. I sat there begging to the gods i dont believe in to not let me face the woman as she has to scan my fleshlight for me. Two tills finish thier sales at the same time, the woman and one of the men, but the man has to clear his till so the woman calls out for me to come to the till and now im shitting bricks. I get there its a normal transaction but im staring at my feet the whole time. I had made space in my bag earlier and i quickly slip it in as soon as the payment goes through and race out the shop. Im walking down the street blasting music in my headphone and stimming like ive done before.
Am i over reacting. I know i likely am but its just something ive never done and it makes me feel like such a perv. Going through the story again has helped me calm down but 15 minutes later (i took 5 to write this) but im still shaking and now my mind just blank for what to do with my day now.
