Denise, I did some limited riding at 3+ months and got in my first 25 mile ride with a friend at 4 months post-op. I'd considered being ready to do a 140 mile ride this last June, however my winter and spring were complicated and so I'm planning on doing that ride next year. Right now I'm on a steady diet of weekly 20 mile fast rides + commuting and find my labia are generally a bit sore after 20 in bike shorts or a day with 10 miles of commuting (wearing street clothes, normal panties).
Going by my experience, you will still be dealing with post-op healing out to maybe 6 months, if you really want to accelerate training while minimizing impact on still tender labia I'd think about borrowing a recumbent bike or picking up a related activity ... hiking lots of hills, stairmaster ...
It's nice to feel training effect again, by end of summer I expect to be leading up the hills again.
Here's a link to my biking thread where some other post-op cyclists weighed in :-)
