How can we make our sex and masturbation better?

I'm a ftm transgender with no surgery done, however I have recently got a strap on so I thought we could use it like it's my actual part.

Also I don't know if this is weird to her or anything but sometimes I wear it to wank off, using the dick to wank off over her when I get horny in the night etc, how can I make masturbation better? (we've been together a year and nearly 4 months, known eachother for around 4/5 years (were long distance so can't really have sex that often)

Any tips?
