Feeling's mutual by the way:

If they used condoms that often, they'd run out of money real quick lol.
Considering Peter mostly doesn't refuse sex, self control he doesn't have
.
He had a similar scene with Felicia, but they were both stuck on the web:

(Spectacular Spider-Man#92)
Was in an era that Spidey's web was so strong he couldn't rip it off for some reason, though you have to ignore why he didn't just break parts of the roof to escape.
Post resurrection it's implied Supes and Lois had sex in Adventures of Superman#505:

There's a scene skip, he's taking a shower, she's getting ready to go out, the bed looks messy...
Next page also mentions that she knows of a ticklish spot:

So that implies, experience.
They probably weren't literally fucking around as much as Spidey and MJ, but there was something here and there.
I don't know Supes as much, so it's very likely other sex scenes were implied around before this.
I think a few times Sue has said she knows the real reason why Reed calls himself "Mr. Fantastic", though I don't know how much they showed...
Yeah, I'm pretty sure that woman of kleenex thing did little to get in the way of their sex lives, hell wouldn't be far fetched for sex scenes to imply they have a lot of fun as a middle finger to "woman of kleenex" lol.
Post-Crisis Supes also wanted Lois to fall in love with Clark, since at the time he considered Clark to be his real side or something like that.
Basically not unlike what happened between Peter and Felicia, and this "my civilian side is who I really am" is from Spidey, since before this, it was Superman,
Funnily enough, Batman got some romance drama as Bruce Wayne in Batman#474 with that Silver chick, though at least they quite clearly say there that Bruce is just a mask for Batman, or at least they do in that issue, but I'm not sure Bruce ever had romance drama like this with his civilian identity before Spidey was around lol.
Their faces on those last panels LOL.
Anyways, all this sex talk reminds me of Spectacular#166, it's kinda funny that MJ starts to feel lonely in it:

To the point she enjoyed another guy kissing her in Spectacular167#:

When, in Spectacular#164, she had sex with Peter:

(She snores here, so I guess that's trait that shows up once in a while after all
)
In the end she didn't cheat on Peter with that Jerome guy, she was confused, but he always forced something, then she told him to **** off.
Doesn't completely excuse the "confusion", but again, at the end she didn't go for it, tried to end it multiple times but the guy kept forcing it.
But anyways, my point is, considering they had some romance two issues before Peter leaves, and she immediately starts to feel lonely once he does leave, it actually looks like they had so much sex she became spoiled lol.
This is all by Conway by the way, wasn't a sudden writer switch that suddenly changed how the characters act.
