What should i do about this?

So I'm 18 years old. People often mistake me for 14 years old because I'm a short person and very scronny. My junk curves downward and makes close to a "150 degree angle" and I worry about this effecting my sex life. I wear boxer briefs and tight pants/jeggings and usually point my junk downward. A few months ago I started sleeping on my stomach with my junk pointing up to my belly button, and nothing changed much, so I started sleeping nude. Baggy pants just irritate the life out of me. If I wear tight pants and If switch to regular boxer instead of briefs then my junk with show through my pants. And I can't stand regular boxers anyway. If I wear my junk pointibg up in my boxers with tight pants it eventually just falls down to the side which is extremely annoying, and I will have to go to the restroom to fix it 100 times a day. So that doesn't work. If I tell my mom I'll die of embarrassment cause I live with her only. I try sleeping nude with it up and it's not working. And I don't know what to do because I most likely will have issues with sex and/or get tormented about it.
