just to clarify, she never brought up the talk and it has remained casual with occasional girlfriend treatment. She will get demoted now. However, starting to wear condoms would require a discussion that i want to avoid to not show jealousy; as i’ll have to enquire if she sleeps with other guys etc.

Also, what do you mean by not letting sex to be a factor?

Which is just as well, as females who make themselves sexually available to males prior to forming a relationship with them usually tend to be psychotic, or mentally unstable. This is why there's the old saying, "you can't make a housewife out of a whore," or a slut for that matter.

I, again, direct your attention to the link provided in the previous comment. The higher a females notch count over one, the lower her ability to pair bond, or form a relationship with a male. While sexual intercourse doesn't seem to dramatically diminish a mans ability to be loyal to a woman, it appears to destroy a woman's ability to be loyal to a man.

I’m 28 and currently seeing a 21 years old uni student casually for over 3 months now. I was spinning other plates during that time. I’m sure she’s sleeping around with other guys, but I never investigated. Notion is i believe she’s young and free to fuck around, but I cannot deny that the idea is bothering me a lot and also i wanted to make sure I don’t get any STDs.

I’m not sure if i should confront her, and how to get down to it. She is great in bed and very submissive. I might have developed some feeling for her and afraid she might flake. Advise is appreciated.

It reads like you're developing one-itis. Whether she, or any female you're dating, has a stable of men to choose from doesn't really matter. You've been dating her assuming that there was competition from the start. If you've been banging her bareback and you're now becoming concerned about potentially acquiring an STD, that's really a concern you should've had months ago. The only thing you can do now is stop going bareback, and consider not letting sex be a factor when you start dating a gal in the future.

As far as confronting her goes, if she hasn't brought up wanting the relationship with you to be exclusive, or doesn't makes references to you as her boyfriend to others, then it's not an option on the table. If you're not the man who deflowered her, or the first man immediately after, it might prove difficult for the reasons highlighted here to get much more than short long-term exclusivity with her, but I fully understand the desire to develop a relationship with a female nearly ten years younger and won't fault you for trying.

The thing is, until you hear her asking questions regarding what, if any, future the relationship has, you're going to have to occupy your idle time with other thoughts to distract you from your nascent one-itis. Consider taking up a hobby the lack of plates provides you. Plan for mothers day. Take your sister out for dinner. Spend time with your aunts and grandmothers, if they're still around. Spend time with your nieces and daughters if you have any. Do this so that if the uni student asks if you're seeing other women before you build up a new inventory of plates, you can honestly say 'yes' before talking about one of your relatives in a humorous way.
