Do you consider yourself "hot"? === not at all!
Why, or why not? === I look ordinary, I'm shaped ordinarily, and I don't FEEL hot (I think a lot of being "hot" is mental)
If you're in a partnered relationship, does your partner consider you "hot"? === We've been married over 45 years now so we are comfortable, so no, I don't think he thinks of me as being hot.
Do you think "hotness" has more to do with physical features and physical beauty, or inner beauty and self confidence? === like I said above, I think it is more mental (and some of that MAY be learned)than physical, but there are physical components.
What's the one change you could make, starting right now, that would make you more "hot"? === I COULD start dressing better! But I am not likely to. I prefer comfort...
