Am i enough?

my gf already has to masturbate to get off. she always tells me harder, deeper, faster! but i just instantly cum when she says stuff like that. i bought her a tiny vibe she picked a black skinny about 4inch long with diamonds on the base. i have put it in her ass, while im in her pussy she was so turned on. the other night i put it my mouth and pushed in it in and out her pussy sucking juices off! she always rubs her clit or vibes it to cum i can never get her to cum inside her, my other ex told me she could squirt but i never got her to a few different nights.
