Could you direct me to any good self love/comfort fics please?

I’m going to assume you mean the other kind of self love, lol.  Hope that was what you were going for, because if it is actually just loving yourself as a person, then I got nothing.  Assuming you mean the other self love, here are some great fics that don’t make you go blind.  Enjoy!

Catch by @copperbadge:
Steve accidentally kisses Tony during a battle. Tony accidentally has
phone sex in a bath. Probably neither of these are really all that
accidental.

All of Me by @blossomsinthemist:
So he was going to do this, he was going to be indulgent and do
this one more time, today, and he was going to think about Tony while he
did it, and then he was—he was going to tell him, afterwards, because
Tony would like knowing that, Steve knew he would, that Steve had needed
to jack off to thinking about him.

The Ruins of Babel (series) by @whenasinsilks: Amid the rubble of their fallen empire, Steve and Tony struggle to find a common language.

Drowning Out the Silence by @stark-spangled-lovers:
“Uncle?” Steve had asked, and grabbed for both of Tony’s wrists, pinning them above his head.
Tony had rolled his eyes. “Yeah, fine, whatever.”
But
Steve hadn’t stood up like he usually did. He’d lingered, and after a
few seconds, his thumb had brushed over Tony’s cheek and their eyes had
locked with an undeniable intent.
And Tony remembered so clearly that
Steve had been about to say something—something that might’ve changed
everything—but the next second, JARVIS’ voice had alerted them to
Bucky’s presence in the living room, and that had been it.
They’d had a moment. And now it was gone.

It would be wrong to wake Tony up.

unintended results by theappleppielifestyle: Tony stares at the ceiling, white-knuckling his pockets. I will not get off to Steve jerking it. I will not get off to Steve jerking it. I will not- That
thought is put on hold as something starts to buzz, and Tony has to
bite down forcefully on his tongue to stop himself from groaning out
loud when he realizes what it is.He shakes his head quickly, takes a short breath in and thinks, I will not get off to Steve fucking himself with a vibrator. I will not get off to Steve fucking himself with a vibrator, over and over until Steve’s whimpers, his fucking whimpers, drown out whatever Tony is trying to think.

Poster Child (series) by sabrecmc:
Tony likes the new poster of Captain America.  A LOT.
