qt, hahaha!
Lynny, it's two in less than 24 hours that you should avoid (as compared to two in one day), so last night and this morning is probably still too close together for him to have made much new good quality sperm!
smiley, I don't think mine feels like a donut! When I started looking the first day I was like, I have no idea what I'm going to find in there. So I had a bit of an explore.

At the end of my vagina, there's a reasonable sized protuberance (about the side of the end of my thumb?) which changes from firm and low down (I only have to put my middle finger in about 3/4 of a finger-length in), to medium (the finger is about a finger-length in), to soft and high at ovulation where I really have to stretch in to find it and it gives way to the touch easily.
I would try exploring again either right at the end of your period, or about a week or so into the TWW - that's when mine is lowest and firmest and most obvious to find. Looking for it for the first time near ovulation, it would certainly be hard to find! So if you wanted to track it (and I find it useful, since I'm not temping or OPKing), I would start at the end of your period and track through one cycle - the changes are the interesting part!
It also made it really obvious to me why at certain times of the month some sex positions are uncomfortable and at other times not! When my cervix is really low and firm I don't like the deep penetration angles at all.
