mainly venting, but feel free to offer advice or similar stories. 

I'm looking to buy a paddleboard to use with me and my dog, and something I would do without my boyfriend (not that he doesn't want to but not something he is into &amp; the board isn't big enough for two people). Part of where my anxieties come in is doing things by myself, in public. Long story short- I was an early bloomer in middle school going through puberty before most of my peers and while nothing physical happened to me, I was certainly sexualized by the boys that were in school with me up until hs which made me very uncomfortable. this is something that has carried with me for the past 15ish years (I'm now 28).  I tend to stay away from summer activities and I can't remember the last time I went swimming somewhere. 

So where this comes in- paddleboarding would mean that I would have to wear clothes that would possibly get wet obviously, not necessarily in a bathing suit, but I can't go in jeans or anything. I am an average looking woman and personality wise, being introverted I don't like exuding sex appeal because I don't like unwanted attention lol. Doing anything that would attract the male gaze terrifies me especially alone and so I avoid doing things I enjoy because of this. My boyfriend would still go with me sometimes with our older dog who hates water so I'll have a safety buddy, but if he's busy, I'd still like to go on nice days because I love being on the water. 

I've slightly strayed from my main reason for posting but I am not sure how to begin to even be comfortable doing things alone. I know its something I need to overcome because I should be able to do things independently from my boyfriend. it's something I am really self conscious about and want to gain confidence in myself to go out somewhere alone.  anyone else in the same boat or going through the same journey?
