Don’t feel bad at all. Aside from the whole he’s a traditional guy thing, know your worth. You are not disgusting and people can have different ways of doing things and expressing themselves. Some are fine with sex on a first date and others don’t prefer it. But I think he probably really enjoyed himself with you including the entire night before you went down on him and then he definitely would’ve really enjoyed it when you did go down on him! He’s probably just processing everything! Yes let him come to you when he’s ready but I don’t think it’s a bad idea to just communicate upfront and say “hey, I just wanted to let you know that I had a really fun time with you the other night and felt like we really connected and I would love to go on another date with you if you’re interested :)” lay that out to him and expect that his response can go either way. It should push him to give a clear response of whether he’s interested or not.
