My husband got a swollen lymph node w/acne in neck, he also got a small rash/cut around anus that bled but healed in a week. Issue if trying for baby?

Fertility. The issues you mention in your question will not effect your husband's fertility. If you are concerned, I recommend fertility testing for both of you so that you can address any real contributors to infertility.
Question. Sorry not clear on what the question is. Dont think it would interfere with intercourse.
