Yes you do have phones on the original sims 1-but not mobile phones.Just home phones.On the sims house party you can call frieds and invite friends and throw a party.So I hope thi helped
EDIT (26/2/2013): There are a few options for home phones within the game, and a few fan-based phones around the net if you're tenacious in finding them. For mobile phones in The Sims 1, there was only one site I found that did that, called Chinafan Sims. They had an english translation of their site, and had a mobile phone store on Page 50 of their Downloads you can put into the game with globals so your sims could use cellphones.
The site is gone, but at archive.org if you put in their URL (http://sims.enorth.com.cn) in the Wayback Machine you can go to a back-up. You can still download the mobile phones and the store on archive.org in their 3 September 2011 save. There are three phone options for the sims: a powder blue one, a red one, and a third one that looks more like a bottle of perfume than a phone. All the global does is the basic functions of the house phone: some services, calling neighbor, calling cab, etc.
Hope this helps, and know that while this fanmade object has worked fine in my game, it might not be the same for yours, so make a back-up before installing it in case it stalls and crashes the game. This object is not endorsed by EA, it was done by a fan.
No not on the PS2 version of the game

No. You can only marry sims that don't live with you, to move them into your family.
No. You just keep making out with the other sim, until it says you are pregnant.
i guess you could do that in the sims1 but you can't make your sim nude in the sims3.
It has semi-mature themes: Sexual overtones (although censored) and a little comic violence
go to the home screen then hold in R1 R2 L1 L2 then enter PARTY M
If you get into a very good mood with very high relationship, (max 100) you can do it. All consoles work.
