I use an app called ReadEra which I like very much. I use the free version but it looks like the premium version does what you’re looking for: it can sync via Google drive and you can upload your own fonts. (Premium is a one-time $20 payment, not a subscription.)

How old is your sibling?

I threw up during pregnancy once when I had just had OJ and brussel sprouts. It was years before I could take even a sip of orange juice without feeling nauseated all over again.

OP seems to be in Europe, so I’m not sure how much of your second point applies.

I don’t see them with boost.

Aw dude, no, flip it around: I can’t imagine having a sexual relationship with someone I’m not romantically entwined with. Real intimacy is about so much more than sex – sex is part of it, but it’s also about trust and openness and what you’ve lived through together… It’s a whole package and you’re focusing on one small aspect & not even looking at the rest.

I’ve been married 13 years. We’re aging. I birthed three kids and my stomach looks bizarre now. We’ve got grey hair, we’ve both had a variety of body shapes and sizes over the years… our love has only grown and the sex has never been better. Don’t take your friend’s anecdote as something that happens to everyone. It doesn’t. (You should talk to someone who works in a senior’s home sometime; people our grandparents’ age are still sexually active despite being pretty far from the bloom of youth!)

I agree with a lot of the other commenters that people in their 20s are nice to look and and can be fun to talk to but also seem like children to me at this point. I couldn’t even imagine pursuing someone so much younger than me; mentally and in terms of experience we’re way too far apart.

Ps. Don’t look at who you’re most physically attracted to & assume everyone feels the same way. I’ve always thought that men hit their peak around age 55.
