Backstory: Been banging this girl (FWB) for about 3 months. I'm 99% sure she isn't fucking any other dudes (I know, I know AWALT, but I have my reasons for thinking so).

Anyway, due to the quarantine, she is the only girl I'm currently fucking (we met before the pandemic). If I'm only fucking one girl, and we've been fucking for awhile, I prefer to go raw (I've had a vasectomy so not worried about getting her pregnant). I know many of you will disagree and say it's reckless, but I hate condoms and I've weighed the pros and cons as far as STD risk.

For the first time we had sex, I still strapped up anyway. But about 1/4 times we fucked the condom slipped and would get lodged all the way up in her pussy (I think because I make her extremely wet and we have rough sex). We had to stop mid sex and she would go fish it out.

I told her "That's why I hate condoms" and she replied "Well you have to wear one".

Fast forward to last weekend and the same thing happened. This time, when she came back from the bathroom after getting the condom out, she proceeded to sit on me and started grinding her pussy against my dick (with no condom on).

I can tell she was dtf with no condom, so I put my dick in her and you know the rest. From there on out we've been having sex with no condom. She never said anything about it, other than mentioning she is on the pill (or so she says, although don't see why she would lie since she knows I've had a vasectomy).

Question is: Does this mean I've raised her interest/attraction level for me, or that she trusts me more? Or any other reason why she would change her mind?

I assume she decided to fuck with no condom because she was tired of them getting stuck in her, but I'm also wondering if there is more to it. Either way I'm happy, but still curious.
