TMI details😅

So my girlfriend/ex (we were engaged but things happened so we broke up and are now working on getting back together) she came over today and for the first time out of all the times we've had sex, this time she showed up with a strap on (I don't even know how small or big it was, I didn't ask the size😅, I might later) this was the first time Iv ever had anything like that in me😳 Iv never had sex with a guy so us using that strap was a whole new experience to me😳 I won't lie I liked it and can't get over the feeling of it and how she looked while we were at it😅 are there any like strap on sex tips out there we should try later?😅 I was on top this time so I'm curious how it'd be if I was under?🤔😅

Uodate: it was 7 inches🤭
