I need help with my dick not getting hard by everything XD

So im 21 now and ever since I was younger I get turned on by everything,so I get easily turned on by everything even flirting or just getting kissed gets me fully hard in seconds,I sleep on my stomach majority of the time and like tight pants that simple contact I can feel myself growing even in public just glimpsing at someone or there ass just for that second if i like them I get hard right there and then and its gets embarrassing,even a few days ago I was just having a normal talk with this one fine looking woman and out of nowhere she grabbed my collar and whispered i was a good boy and fuck it was embarrassing because she just walked away winking at me and I have a very big praise kink im glad she walked away because I had a throbing tent thats why now I've been wearing long coats or jackets to easily hide it now plus im not good with flirting or taking compliments turns me on and I mostly just freak out or freeze in place would love to talk to anyone about it that has similar problems or advice lol
