Your electric will be fine.
You might find it's too hot for some things (melts the insulation on your wires, turns solder dull or dark too fast, etc). If so, just get an ordinary lamp dimmer to cool it down.
If you're going to do lots of work, or try to assemble parts on boards, or do any really fine work, you'd be wise to invest in a temperature controlled iron. But for soldering a few wires here and there, you're fine with what you got.
Gas irons may be fast, but I'm betting that waiting a minute or two for an electric to heat up and five for it to cool down isn't going to be a problem for you. It's cheaper to operate, and there's less to go wrong with it. With good care and light use, it should last years with no more care than keeping the tip tinned.
That's a little tip right there - always keep the tip tinned (coated with solder). The tip will last many times longer.
1. Heat up.
2. Wipe on wet sponge.
3. Solder.
4. Tin the tip.
5. Put it back in the holder.
6. Turn off when done.
By the way, electrics can be fast too. My Metcal melts solder at about 25 seconds, and is ready to use in about 35 (just timed it). Oh, and my ancient, inherited Weller Junior soldering gun (with bakelite case!) melts solder in less than 10 seconds, and the tip can be handled 30 seconds later. And I use a lead free solder (SN100C) that melts at 227C, not tin/lead solders 63/37 (183C) or 60/40 (183-190C). The times would obviously be less with the tin/lead.
