During foreplay my boyfriend was stroking himself and I'm fairly certain he was putting a finger in his a. I noticed it once before but couldn't tell if he was rubbing his bas or had a finger in himself. I don't want to ask him incase I'm wrong. Or incase it would embarrass him. I was thinking about maybe just trying to stick my finger in him and see what happens. But not sure if there's etiquette about asking first......?? I personally wouldn't want anyone doing it to me if I wasn't expecting it. But not sure how to approach this. Also, if I do insert it does it just go straight in? Or am I supposed to angle it. I've never done any anal stuff. Please no rude comments. It was embarrassing enough asking this. Thanks in advance!!
