A virgin going to get married

I've had relationships before and slept with girls but never penetrative sex or genital action.

Been having this in my mind: do girls like to suck dick?

to a guy, seems pleasurable, but I'm asking myself does a girl like sucking on something that just had my urine on it.

how do I prepare for sex? do I trim/shave my genitals?

Im a 28M getting married to a person(26F) who's never had a relationship before. it's got me wondering? what she has in mind

I have 10 more months to my marriage, I wanna hear up to give her the best first time of sex, how do I prepare myself? workout? stop masturbation till we have sex?
