Pubic area & shaving

So I just went to the bathroom and noticed a lot of red bumps under my pubes. (I’m a virgin so it’s not any std or stuff like that) I’m wondering if it’s the soap I use? I don’t remember the brand I have but it doesn’t really have a scent & it is a bar. I also would love to know some tricks and what products to use to shave down there Bc I always have ingrowns and razor bump but I don’t shave against the hair anymore.
