This is the problem with a sex forum that censures swearwords related to sex... Lots of you aren't understanding the OP at all. She's not having sex 4-5 times a day, she's talking about masturbation. She may well be a troll, but let's give her the benefit of the doubt ok? Innocent until proven guilty. If nothing else, it will make for a lively discussion.
Talking to you now Casualilikeit, girl to girl (or to troll, who cares):
Personally these days I masturbate once or twice a day, but there have been times especially when I was without a bf when it was more like 3 or 4, so not far off. I don't think you are completely beyond the norm, but how about trying to have less sessions but climax more times in each session? Can you not have multiple orgasms? A typical session for me is usually 3 to 4 orgasms, but with the right toy or when I'm really horny it can be more (a few nights ago I had 8). I can tell you, after a session like that you'll feel plenty satisfied and it will keep you going for at least half a day.
If you already have multiple orgasms and still don't feel satisfied, then I'd say maybe you are addicted. If you are, no shame in that, but it has to be treated like every addiction: see your GP (embarrassing I know but they'll have heard it all before) and see what help is available, but tbh there's probably nothing, apart from a year long waiting list for counselling which in the end will do nothing for you.
The advice you already got to get a bf is probably the best one. You need good, long, hard sex, and even if that's still not enough, your bf will love to see you touch yourself all the time, mine can't get enough of it!
