I'm a straight-ish dude, so usually just had sexual encounters as the penetrating partner. I had to insert a suppository for the first time in my adult life. I wasn't looking forward to it but not dreading it either. It's medicine, so whatever. Read the pamphlet, followed the instructions. Felt a bit weird as I gently pushed it in with my finger and then this weird wave I can only describe as....Interesting? Fully half an index finger in, I felt my chest get heavy and get rock hard. Immediately more turned on than I have been in ages. Now I'm just confused, bricked up and debating the urge to jerk off with 4.5 cm pressing IN ME??? Yeah idk what happened but that did something to me and I have to spill because this info ain't going to anyone I know.
