A high sex drive is a problem only IF it affects your capability to function in your daily life. If you are able to concentrate at work and lead a "normal" social life, then it really isn't a problem ... except that of finding a willing and able partner
Likewise, if you are happy with who you are ... highly sexed, wanting to indulge in "slut" role-plays, then there really isn't a problem (although this one is rather tricky as it is hard to seperate undue influence from your close ones). It is only a problem if you are unhappy with who you and/or have self esteem issues.
So If you find that it affects your ability to work/socialise normally, or if you have self-esteem issues, then you may want to seek help.
I've met quite a few high sex drive women in my life ...
One was my gf when I was serving NS. We would fuck like rabbits during the weekends but during the weekdays, when I couldn't bookout, she would be incredibly high-strung and sexually frustrated. Masturbation didn't fully satisfy her but she made do by scheming on what we would do on the weekends. It certainly made for rather explosive weekends
Another was a girl I knew in Uni, while in hostel. She had a bf but couldn't enough even thoughly they did it daily. She started trawling campus for guys to fuck and it all spiralled down from there. Her bf was not supportive, she could not reconcile her shame of sleeping around vs her desire to fuck. She ended up needing help and medication. It messed her up.
Bottom line, if you find the right people, in the right environment, you can be happy. If you find yourself doing the wrong things for the wrong reasons, IF ever you are unhappy with who you are or what you are doing, force yourself to take a step back and evaluate your position from a 3rd person's perspective. Don't be shy about getting professional help. They often give you a perspective that your friends usually don't. More info means better decisions.
Also, don't bother about what constitutes "normal" masturbation or sex preferences. We are all different. We prefer different positions ... different things excite us, motivate us, stimulate us.
Some of my gf's could multi-orgasm, some couldn't. First time I met one who couldn't, I kept stimulating her after she came, insisting that she come again. I got a shove, a slap and a scolding for that. Some of them like to use fingers while masturbating, some didn't. Some liked digital penetration, some prefered clitorial stimulation. As for what goes on in their mind, the variety of thoughts is stagerring.
You figure what works for you physically and mentally and leave it as that. Don't try to benchmark against other people.
BTW, sports ... I find that sports actually increases my sex drive! Other than the initial "aching-all-over" getting fit period, sports rarely leaves me so tired that I can't get it up. OTOH, the competitiveness makes me more driven, more alive and it carries over into the bedroom. Sports also de-stresses me, which leads to more mental inclination for naughty stuff. Sports also makes me fitter, which means more energy and stamina for *ahem* nocturnal sports. These days, I find that I am actually buzzing after my weeknight sports sessions ... to the extent that I actually have trouble sleeping unless I *ahem* release first. That's me anyway. YMMV
