A tomboy bra question?

-So I'm a serious tomboy. I always have been too. I sometimes shop in the boys section, I'd rather hang out with boys than girls, and I've never been afraid to get down and dirty. Even if I don't sound like it, I totally am a tomboy. And because I spend a lot of time outside, or running around, or playing sports I really like tank tops. There's just one problem with tank tops and that's that your bra strap ends up showing. And even through I'm only an a cup, I really like the support of a real bra. And I need it too, like my boobs are pointy or something because I just can't do a sports bra or just a tank top. My boobs don't look regular unless I use a real underwire bra. But I hate feeling all exposed with my bra strap showing. But, I found these amazing bras where you can jusy take off the straps and it becomes strapless. So I can be chillin in my bra and then just like, put on a tank tops and take off my bra straps. I LOVE IT. but I heard that most people hate strapless bras. And I'm a tomboy so I actually don't really enjoy bras all together. So I was just wondering if it's normal for a person like me to feel comfortable in a strapless bra and be able to wear it all the time. Also, is it ok that my bras are all colorful. I think they look kinda cool. I have a plain gray one I wear a lot. But the other one I wear is pink with blue polka dots. Do any other tomboys like colorful bras? Sorry if I sound stupid or if this is too long. I just want to know why I'm the only person who's in love with strapless bras. Thanks in advance!Until I read the last lines I was going to suggest strapless bra. Im a girly girl but wear strapless bras. It looks funny when the straps are showing!
