Yes that's what the acronyms mean.
And no, there are unfortunately no tags for that (though there are at other sites and should be here), but you can search using the big tits and transformation tags and you'll at least find BE that way.
I think I left out Dungeon Slaves as a recommendation. It features BE, big dick, and futa PE.
I'm a 100% healthy, normal, cis het guy, and I admit that PE seems like a pretty weird fetish to have. It seems like "Well he must be gay." or "He must be insecure.", but it's just not so. I like pretty much any transformations towards an exaggerated or idealized physical form ... in fact I'll list my likes and dislikes here. I'm not sure why I'm writing all of this except that you seem to be concerned about the fetish and I don't think you should be because at least most of them are pretty normal. Maybe this can help you or others.
Things I don't like:
- giantess growth or tall girl
- sissification without full gender transformation
- fat growth aka "weight gain"
- age progression
- age regression beyond some indeterminate point like upper teens
- excessive butt growth
Things I like that represent exaggerations of normal sexual dimorphism ...
- BE
- PE
- muscle growth (male & female, but especially male)
- male height growth, virilization, etc.
- female lactation, beautification, increased fertility, etc.
- female shrinking / minigirl
- pretty much any exaggerated masculinizing or feminizing effects
- female age regression and facial neotenization (within limits)
Other stuff:
- I like futa based stuff, but didn't before I got into these sorts of games (they corrupted me!), but for me the penis in that case represents not a male appendage but an increase of the female's libido, hypersexualization, increased awareness of and connection to her own desire, willingness to take action on her desire, taking agency in her own reproduction, etc. So it's a physical change but it's symbolic for and representative of a behavioral-psychological change
- some bimbo stuff ... I'm not really a fan of women getting literally stupid, but I do like the idea of libidinization, losing control of sex drive, sex crazed, etc.
There are lots of sites dedicated to these kinds of fetishes but I don't think it's within the rules to list them here, even though they're all perfectly legal (ie. no p*d* crap).
