As long as you haven't been rotting away doing nothing with your life it really doesn't matter at all, as there are a whole assortment of variables that result in people being very late when it comes to having their first sexual experiences.
I didn't do anything with a woman until last spring, I'm 28 now, and looking back on how my life progressed it'd be extremely obvious to see how I was denied of such a basic experience for so long.
When we moved to a new town and to say the least I didn't fit in at all. Literally no one would talk to me and because of that I never had even the slightest chance of developing the skills and experiences necessary to interact with women. Prior to moving to this town I was a normal kid with a lot of friends, actively participated in different sports, clubs, etc. Anyway, during high school I got a really good paying job and focused on that and later working out when I was a bit older, so these years were both very good and very bad in different aspects.
After graduating I continued working through my late teens and into my early twenties. I had taken some courses at my community college part time from 19 to 21 and later did a full year at a local 4 year university, which I commuted to. Looking back if I was more proactive socially back then I would have had a lot of opportunities then but wasn't really in a place where I was interested in that. Prior to going to the 4 year my exposure to people my age, let alone those of the opposite sex, was practically nonexistent. I literally went months without seeing anyone remotely my age, mostly people in their early 30s and up, opportunities with the opposite sex were an extreme rarity to say the least.
Through my mid twenties I had other things that I was focusing on and wasn't in a position to meet women at all. Then in the latter part of 2016 on this changed and in about a 6 month time period that involved actively working on approaching and interacting with women I was interested in it eventually gave.
If I told most people about this in real life they'd be shocked that it was so late, as they most certainly wouldn't picture a guy like me being in a predicament like that, if you'd even want to call it that. Also, I'm genuinely not attracted to the majority of women and combine that with the fact that many have issues, plus the set of circumstances I was in, it's very easy to see how it happened so late.
